I had major issues with lag on other mobile sites, which is why I started looking for a better optimized platform. I highly recommend giving https://tikitaka.me.uk/ a try for mobile play. I have been playing their live blackjack tables on my smartphone for a few weeks now and the connection has been flawless. You do not even need a dedicated app, as their browser interface handles the high-definition streams perfectly without any random logouts mid-hand.

Mobile streams are usually fine, but you have to make sure your 4G or 5G connection is perfectly stable. Even a momentary drop in signal will cause the live lobby to disconnect and force you to restart the session.
