Streaming Problems with Chromecast

Hi there,

Since the beginning of Februrary when casting Youtube to the Chromecast the stream ends shortly after the FP4 display goes dark / into standby.

This only seems to happen when streaming Youtube (other apps like Nebula or Disney+ work just fine). Other Android Phones or Chromebooks work fine. Viewing on Device works just fine. When waking up there is a “toast”-message about a Network error which disappears too quickly to read.

I assume that this is mainly a fault in the Youtube app (but as usual google does not react to bug reports :-(), but it also seems to be FP4 (A11) related.

Has anyone an Idea what might cause the problem and how to alleviate it?

Regards
H.
