Is this happening on 1 specific casino only or do you get the same error anytime you play the same game from Evolution in other casinos too? I'm not a fan of live table games so I play it rarely, I have no idea what is going on since you said that you can play other games so it is something weird imo. If provider had already told you that it is related to the casino, means that the casino is the only one who can fix the issue. Maybe you need to try in other casino first to know if it is really an issue with the casino or an issue with the specific game by evolution gaming.
I don't think all casinos do the same thing at Evolution Gaming because of course customers like OP who always get consecutive wins cannot always be found.
Maybe because he had too many consecutive wins with quite large amounts, that was one of the reasons why he had this problem, well maybe there were restrictions placed on him by the casino team.
Some time ago there was also similar case but not in live table games but in sports betting, he also explained the problem here but it is difficult to understand how restrictions can be made because if large casinos are used then they will always be fair to all its customers without exception.
I tried betting on live table games several times but never had the same problem, maybe this only happened in one or two casinos and what is clear is that I always use trusted casinos that clearly have very good service.
It true that trying to play at another casino might make it easier to find the answer to whether the same gang problem also occurs in other places.
