Here’s something peculiar I’ve never seen before: yesterday I completed a very long walk. The last two miles only show up on the LifeMap at a resolution of 1 mile or greater; if I zoom in any closer than that (5000’ or 3000’ or closer) the last two miles disappear, replaced by a faint line between the point where they disappear and the terminus of the route.
If you share your profile link, I can see if a LifeMap rebuild fixes the issue
This happens to me occasionally, but it’s more a matter of the higher zoom levels just take longer to generate. A delay, more than broken forever.
