Since the update devices cannot connect to my S21 Ultra. I have to unpair the device,  restart my phone and try to pair multiple times before it works just that once. 

I have to repeat this any time I want to connect to that device daily. 

I've read some issues with WhatsApp, but I do not have that app on my phone.

I am having the same issue. I can get it to work for a few hours by resetting the bluetooth and wifi cache in settings but as I said it is only for a short period of time. I thought it was a Uconnect issue on my car but when I tried to use my Buds 3 Pro to make a call in the car I noticed they would not connect either.

EDIT - It may be that the issue occurs as disconnect. If I never walk away from my phone my watch never has an issue. I am going to test with my Buds 3 Pro

I have had some success with a total reset of my 21 Ultra. I still have to restart from time to time to reconnect but I don't have to reset my BT and Wifi. I hope this will help some of you and I hope that Samsung has a fix for this soon. Flagship devices shouldn't have to put up with something like this even if they are getting their last major update.

Seeing similar wifi and bluetooth problems on my s22. My watch is constantly disconnecting and barely lasts a day because of it, when it only used about 30% prior to the upgrade. A few other bt speaker devices will no longer connect at all.

I've been having similar issues with my s22 and the new upgrade to Samsung. Will not connect to my Ford 2011 f250 (sync 1). Tried to upgrade my Ford software. That did not work either. My friend connected via Bluetooth with his iPhone and it worked just fine. So I isolated that it's a Samsung thing. Any additional advice on how to fix this other than waiting for a software update?

Same issue here s23 ultra. Will get it pair once then fight it the rest of the times. It won't let me pair for calls but will for my audio only. Not showing my music on my ford sync. Updated my sync still nothing. The new update is trash. My company phone has no issue at all pairing up. But that's an iPhone. So I feel a switch coming soon.

Constant disconnecting of different BT devices. Having to restart phone to at least get connection for a short time. Issue started after update. Samsung is recommending a factory reset and that is not going to happen. Samsung really let us down and for the first time ever, considering a different Android manufacturer.
