Hello @Dirk_De_Taey,
Thank you for the detailed report and for taking the time to describe the behavior so clearly.
This issue is already known and is being actively worked on. A fix is currently in QA testing, as noted in the related Community thread. We recommend keeping an eye on that thread as well as the Software Release Notes (both Production and Early Access) for an announcement once the fix is released:
Once the fix is available and released, please update the app and test again.
If the problem persists after the fix has gone live, let us know here and we’ll be happy to follow up with you.
Thanks again for your patience and for helping us improve Roon.
