Vera App and bluetooth car kit

I’ve noticed for a while that sometimes when I get into my car, my cars bluetooth decided that I’m in a call already and switches to my phone’s audio, as if I’m in a call. Took a while to figure this out, but I pinned this down to the Vera App being active on my phone (iPhone 12, iOS and Vera App up to date).

I have to ‘kill’ the Vera App as a background app, which at that same time ends the call on my car and hands me back my Car Radio sound.

As far as I can figure out, the audio feed in the Vera App might be originating from the Vistacam 1203 that I have on my dashboard in the app.
