Thanks for the response. I just submitted the bug report; here's the FB number: FB14036822.

I appreciate the thoughts / example! It happens pretty rarely, so it doesn't seem like it's an errant key. But still worth looking into.

Thanks for the info! I'll definitely check out that video.

Update from later - using Activity.activities (instead of simply referencing the local activity variable) when ending the live activity fixed this issue. Thanks!

Thanks for the response - please see my reply below (as it was too large to leave as a comment).

Thank you so much, this helps clarify a lot! It appears as though if screentime is disabled, then Phone is the only "allowable" app; if screentime is enabled, however, it appears that Phone, Messages, FaceTime, and Maps are "allowable" by default. Are you able to confirm this, or does it vary by user / device?
