Lifestyle logging reminders stop working after a few days

Same here. Finally got it to work a couple of weeks ago (after installing version 5.18) and every now and then, notifications fail to work for a day or two.

I know reminders and stuff work with this app, so maybe the source code has some clues on how to fix the issue? github.com/.../Calendar

Same here. Or rather, the morning notification still works, but not the evening one. I've verified that both are still enabled.

Edit: Neither works now

I have the same issue. 

Interesting. For me, both are enabled but neither works

I'm having the same issue with missing Lifestyle and Health notifications. My Fenix 8 Pro displays this information in the notification center, but I don't have anything on my smartphone. There's also a problem with some voice notifications during training (e.g., power is spoken by the voiceover, but heart rate and pace aren't). This is a Garmin Connect 5.18 issue. I've already reinstalled the app, and clearing the cache doesn't help either.
