Audio dropouts when playing TuneIn stations after some time

Running fw. 4.6.337862.30 in a S50 pro+ there are random dropouts in the audio when playing TuneIn stations for a while. I use the S50 pro+ as a master and several V3 mini’s as slaves. The mini’s are running fw 4.6.337862.29.
It can be resolved temporarily by pausing the audio for a few seconds and then press play again, so it looks like it is a buffering issue. When resolved, the problem may disappear for days.
The dropouts are present in all connected devices in the group.
Anyone experiencing the same issues?
