Im running latest Roon 2.0.7 and on my Galaxy S21 Android phone the Roon app hangs everytine I try to change the order of songs in a saved Roon playlist by drag and drop. It seems to work perfectly on iPad Pro and Windows 11 PC.
I and others have a similar issue with iPhone.
On iPhone Roon crashes as soon as “the dots” are touched when trying to sort playlists.
IPad works fine.
This issue was reported to Roon a few weeks ago and they have acknowledged it and are working on a fix.
I’m not sure if Android was mentioned in the thread support acknowledged but you could search the forums and check.
