YES me too, my phone and my tablet had been able to use multi control even after my phone (s23fe had the one ui 8 update), then recently, it stopped working my tablet (tab s10+ (one ui7 at the time) just could not find the device at all. At first i thought it was due to the tablet not have one ui 8, so i updated but still didnt work. Ive checked bluethooth, wifi, account, cleared cache, checked apps, reset Bluetooth, have my mouse and keyboard re-paired but nothing worked. The only thing i can think of that i bought and conneted the galaxy watch 7 to my phone and tried to connect it to my tablet (samsung dont allow watch to connect to galaxy tab). I tried reconnecting my phone to tablet bluetooth and the other way round but it only shows as bluetooth data thedering. Its so annoying. Dex on my tablet also keeps asking for an external display. I am mostly very annoyed of the multi connect not working. The tablet and the phone also cant seem to connect to each other: none of them show up on each others nearby devices screens. The tablet and the phone both cant seem to work together too, although samsung flows works. For me mainly the problem is the multi control not working
