Yeah, but usually just level 1 data the site will give the option to change.
I think around 90% have the ability to update or change the data as long we are not putting level 2 verification yets. Level 1 now already being used as mandatory account for each casino, even a new one like (WHALE Casino) required us to fill those in the beginning.
But, we still can change in the setting. If people worried about can't change the data, my advice before you putting the data ask in the live support... It's the casino have ability to change or update the data or not.
