Description of Issue

Until the most recent Roon update, the system worked flawlessly. Abruptly after the most recent Roon update loaded, all previously functioning remotes were suddenly no longer able to connect to the core but they continued to recognize the existence of the core and attempt to connect to it. (See attached image)

This abrupt dysfunction happened simultaneously to both iPhone/iPad. The core computer has continued to remain fully functional and continues to access both my NAS stored music files and Tidal streaming.
