Thanks for sharing your report with us, @kursaal!
May I ask that you please provide a brief description of your current setup using this link as a guide.
Make sure to describe your network configuration/topology, including any networking hardware currently in use, so we can have a clear understanding of how your devices are communicating.
In addition to the setup details above, may I ask that you also confirm the following:
- Just to confirm, this happens with all Airplay zones, correct?
- When did you notice this behavior? Has it always happened or is this a recent experience?
- Have you tried rebooting the Core machine, networking hardware, and airplay endpoints?
Regards,
Dylan
