After never using a pin to log into my S20, my phone decided to lock me out. I had just installed the newest update. To me, this seems like it's tied together. Unfortunate for me, Samsung members that I spoke with on the phone didn't have enough training to figure this out (entry techs). I tried the basic 000000, 111111, 012345, 123456 and none of them worked. Has anyone ever ran into this?
I have the same phone and the same issue. I'm still locked out so I haven't found a answer to this. It appears its some sort of new security. That's all I know and I'm not happy. Did you resolve your problem?
