Description of Issue

Was working fine until the update. Now i cant connect to the core with my phone. Its stuck on the “looking for your core” screen. It wont accept ip or hostname to scan either. This is very frustrating! Please help. Not very tech savvy

Go to Roon - Settings - About and see if your core and phone are on different versions of Roon.
