Online casino betting limits: why do they change without notification?

noticed the table min and max bets shifting randomly on a few sites, especially at live dealer poker. had a decent spot at a mid-stakes table and then boom, next session, minimum buy-in doubled and max was slashed, no heads-up from support or any site notification. i save all my deposit screenshots and check logs so it’s not just me missing something.

i get that casinos wanna manage risk and maybe steer action, but the no-warning changes get frustrating if you’re tracking stats or trying to play some consistent game theory stuff. has anyone actually gotten a clear answer from customer support about why or how often they can change betting limits? are there any patterns or is it just up to each operator?
