no notifications, no weather data

I moved from android to iOS, and I am beginning to question, in general, if there is something that actually works 24/7. Watch is epix 2 pro an iOS is 26

The issues I have with Garmin Connect is that  I get notifications sometimes, also the weather data in my watch face more often says '--' than actual data.  Everything is enabled, no battery savings. I must be missing something?
