The version I’m using is 923, and when I try to update 931, it doesn’t update and remains as 923.
And even after restarting by clicking ‘Click here to relaunch’ as above, it is still 923.
I have previously installed Roon Core on my PC and have moved the backup to NAS Synology DS920+ to use it.
However, it says that another core is being used as shown below.
It appears you are showing two instances of Roon running on your Windows PC (two Cores, two Remotes, both sharing the same IP address). Is this accurate? Can you close the Windows applications and restart the Core and see what shows up? Are you running the single Windows app or separate Roon Server and Remote apps?
