I hadn't synced my phone in a few weeks and now I want do but keep getting the message that it can't connect to MB . It says "server not found. Ensure MusicBee is running..... etc etc" I updated my MB on my computer thinking I need the newest version but that didn't help. I have newest as found on the Newest Version thread in the forum. I closed out and re-opened the app and the program several times. Even double checked my port settings on the router.
I'm using a Galaxy S21, Galaxy 9+, Galaxy S7, a Galaxy Tab S 8.4, Poweramp, and Musicbee.
