Spotify/Chromecast (and spotcast?) Problems

Hi, I have two new Nest Audio and one Google Home Max, all three connected to Home Assistant.
Additionally, I installed spotcast a few weeks ago.

Unfortunately, I do have several issues:
Spotify stops playing every now and then, but only on some days. I think it doesn’t matter if I started over phone/spotify app or over spotcast. But you can see it perfectly in home assistant, purple is “playing”, cyan is “paused”:


In this cases, I just have to press play again.

Additionally, when I open spotify on the phone and try to cast to my speakers or speaker groups, it sometimes does not show all of them or is not able to connect to them. And when I look at the Logs in Homeassistant I see a dozen of errors every morning.


at the end of each log line, “xx mal” means xx times. So the first entry already appeared over 300 times.

I do not think it is related to spotcast, since some of the issues were already before.
Anybody has any idea on this?
I would like to reduce the errors, but most of all I would like to use it without any problems…

Thank you,
Stefan
