Max bet rule during bonus

so i grabbed a deposit bonus at one of the crypto joints last night, which looked fine print-wise, except when i got to blackjack live dealer it wouldn’t let me go over this random max bet. not just per hand, but like if i tried to split or double the system says “over max bet for bonus play.” never had a site lock down the bonus rules like that - usually they just threaten to void your winnings if you go too high. this one has tech in place, so i couldn’t even misclick if i wanted.

i get the point is to stop people from yolo’ing their bonus balance in one swing, but it basically forced me to grind $10 hands over and over. i got so bored i started naming the virtual chips, which is the level of life i’m at now.

anyone else had sites actually restrict your max bet at the table during a bonus? is this getting more common?
