Having same issue with galaxy S23u. I've reset the pin at least 6 times and I am still unable to use the pin I want! Does it have to do with work profile I wonder? Surely Samsung has pin history requirements they can share. I'd hate to have to reset my phone just because I want to use an old pin.
I have same issue and it seems nobody found a solution.
This is just one more topic on Samsung Forum where users ask/request things and Samsung does not pay attention. They even cannot afford a team to manage the forum and answers the main questions...
