I know exactly what you mean because I had the same struggle until I found a site that is actually optimized for mobile. Everything is easy to tap, the menus are straightforward, and the odds load quickly without any annoying lag. I have been using https://www.dubibet2000.com/en/ on my phone and it has been a much smoother experience. The layout adjusts well to the screen size and you do not have to zoom in or struggle with tiny buttons. They cover a wide range of sports and the live betting section works just as well on mobile as it does on desktop. You can browse without signing up, but if you create an account, you can save your favorite events and get notifications when odds change. The overall experience feels natural on mobile, which is something I cannot say for a lot of other sportsbooks I have tried.
