After following samsung customer care for weeks, and lots of research, I came to a conclusion that samsung intentionally pushed an update that damaged our Spen( note 10+) Bluetooth functionality to sell their replacement Spen.
Or it could be a Quality issue of their spen, that are meant to last for a few months or 1 year maximum..
We note 10+ users are cheated by samsung.. Also s20 series faces serious greenish display issue, and Samsung is charging for the display replacement if is it out of warranty..
Seeing all these, I made up my mind to not buy a Samsung phone from the very next time.. Because buying a 85k worth phone and Samsung is ignoring us like hell, and their customer representatives are behaving like a robot..
My brother have iphone 11, he purchased it at 48k only, and he is too much happy with his device..
I am facing the same issue. I already rebooted my phone, reseted the spen, and checked the updates regarding the same. Many users are facing the same issue and theres an article about it on sammobile. Apprerantly theres no fix yet. So i guess we should wait for the next security update as last one didnt cover anything.
