Basically, yeah, that Strava data was removed when you revoked access & there wasn’t other data present in CityStrides that would make up that progress.
There’s a lot to consider…
- Garmin limits access to old data - see Where are my older Garmin activities? - so be aware that if you revoke access and then re-add your account, that 5 year limit is based on the date that you re-add Garmin to CityStrides not any other date
- I might be able to get Garmin support to re-run the full sync for your account, so you wouldn’t have to do anything other than remove Strava … I say “might” because I’ve never asked for a full sync … oh, and the background info here is that they also only let me request data once so I can’t just run a full sync again like I can for every other service
- Deleting data is pretty slow/“expensive” so if you do revoke Garmin access, you must wait until all of that data is gone (their logo is removed from your profile page) before trying to reconnect
- You must keep Runkeeper connected during this process because if you get to a state where you have zero connected services, then your entire account gets deleted
