Great news!
[UPDATE: 4/28/2020] The activity showed up within 24 hours. I wasnāt diligent in checking, so I canāt be more specific. [End update]
My first delayed activity came this morning.

I donāt think I did anything different. I have not edited the activity (although I will, changing the activity from āRunningā to āStreet Runningā and the type from āUncategorizedā to āTrainingā. But Iām leaving it as is until it shows up in CityStrides so youāve got a clean slate to work with.
Another quick update for everyoneā¦
Thereās a timeout/error occurring in my receiving their notifications. This endpoint is in Amazon Lambda, so debugging this is like finding my way out of a byzantine labyrinth thatās filled with snakes. Iām working through it, though.
Edit: looks like their style of sending the full activity data in their payload exceeds the Amazon Lambda limits. Thatās at least part of the problem, anyway ā¦ I donāt know how Iāll resolve this, but I at least have a lead.
Now, the most useful information for me is your CityStrides user profile link and the day that the activity occurred on (and the day that the activity was saved to Garmin, if those are different).
Thanks for the updates James!
Update - I am only missing a run from April 25th now. Syncing for all recent runs has been instant!

Itās been 90 minutes since I uploaded to garmin and I still donāt have anything. This is supposed to be the last street in my city so Iām very interested to see it upload. 90 minutes seems pretty long to me.

Awesome job, Jeremy!
Seeing that 100% show up is always fun.
There is a post further up where James talks about some of the technical challenges he is facing. I donāt understand what they mean, but We should try to be patient as James is still kind of in the Beta stages of this Garmin integration. We canāt forget (or if you didnāt know,) CityStrides is a hobby side-gig that he does in his spare time.
Alright 
So 
Today I Learned that Amazon Lambda has an upper limit to the size of request you can send it.
This, paired with the fact that you all run too much, meant that Garmin was sending me notifications that were breaking Lambda.
I sorted this out by moving that onto the server.
Garmin automatically retries sending these notifications, so ā¦ hereās some live footage of Garmin and my server right now:
This will take some time, but Iām pretty hopeful that all these activities will all arrive in CityStrides soon*
*Overnight, probably 
weāll see

Thanks James, does this cover all activities since we went live with the plugin (Friday for me)?
I checked this morning and my account is now up-to-date with all lagging Garmin activities synchronized.
Thanks!
My run has shown up but seeing that 100% show up, which Iāve heard is fun, has not happened yet. 0 incomplete streets and 99.87% complete.
20 hours ago I ran the length of a parking lot because citystrides thinks itās a street. Fine, whatever. 6 hours later the run finally uploads and I see that Iāve missed a node because that node is in the middle of a house and I foolishly only ran up to the fence and not through it and into the house. Fine, whatever, mark it manually complete for a very unsatisfying end to running every street in the city. Profile still shows 99.87%, probably cached, surely all will be good in the morning. Wake up, 99.87%. In a system that tracks and reports percentages, the act of getting to 100% is the pinnacle and this feel like anything but.

Activity: 6 hours ago (0738 28 April 2020)
My first run on Garmin went through in seconds (on Sunday). I have paused Strava.
I connected with Garmin last night, ran early this morning but nothing came over to city strides. Itās been about 2 hours. What are we seeing for usual time to upload from Garmin to cs?
2 Garmin activities yesterday. 1 walk in the morning around 10am, 1 run the evening around 5pm.
Last night after 8pm, still did not see either activity. Saw this thread and went to bed, planning to post in the morning.
This morning ~7am I do see the two activities, BUT no streets are complete, only progressed. There are definitely completed streets on both, as all nodes are green on some streets, not all. Morning walk is showing 13 progressed, evening run is 16 progressed.

Thank you @JamesChevalier!
Had same issue. It later changed to show some complete but took a long time. And my overall percentage in my city didnāt move despite the completions. In my case the only way I can even get anything to show in cs is to do a one time missing activity sync from Strava. Direct Garmin doesnāt seem to work at all

Hi @pgillis24, so your streets did eventually turn complete? Thatās good news (for me), maybe Iām just not being patient enough. 
First time I had activities with Garmin, sync was very fast. But fewer users, so I suspect a few kinks are surfacing, which is expected.
Thank you for posting.
PS. Iām going to hold off on the manual sync to see what happens.
