After I read your post, I immediately opened the site and I tried to play the manual with Multiply BTC (wait, I claimed first for the free roll 😁). I rarely play manual here but I made it for you today to test if there is a problem. Below you can see the screenshot I took of the roll history, you can see there the time interval of my bets. And I can say that I played well and there was no delay in releasing the result.
