Hmms ill be watching this one, it might be a good idea to reach out to the site and inform them of your post.
Also id say wait a bit longer if there not auto transactions then there could be any number of reasons.
Like the hot wallet holder being busy or anything else, i know in some cases casinos would favor paying out the small withdraws instead of the big ones.
If they know that transaction is going to clear out the hot wallet and leave many peoples transactions in limbo.
1 person complaining is a lot better then the whole site.
