Some bugs: raise to wake, sound alerts, treshold, Spotify

I don’t know whether this is a known bug or if it has to do with some feature I’m not aware of. But here’s the issue: when I’m running an interval workout, in the last five seconds of each interval the watch vibrates to warn me that the interval is about to end, which is great — what’s not great is that during those five seconds raise to wake doesn’t work. The screen stays completely black and only turns back on and works properly with raise to wake after the new interval starts.

Two other problems I’ve had: the audio alerts stopped working halfway through a run and only started working again after restarting the phone during the run. Before restarting the phone during the run, I changed the alerts to the watch speaker and then they did work again.

Still about alerts: sometimes they’re in English, sometimes in Portuguese. I don’t change anything — the language switches by itself. It’s strange.

I’m also having this issue: my threshold pace was updated on the watch at the end of a run, but in the app it didn’t - it shows the old one. Threshold power also updated after the run and that one was updated in the app. Heart rate treshold is the same in the app and in the watch. So: only the pace treshold is wrong  

Final bug: Spotify sometimes leaves the watch screen completely black, and the only way to fix it is to swipe on the screen or change the Spotify audio output to phone control (by pressing and holding the down button).
