Had exactly that problem for months before finding something that actually worked for both. I use https://1xbetbd.com/ and it covers sports betting, live betting, slots, and table games all under one account. Switching between sections is smooth without the page freezing or reloading everything from scratch. Mobile version works just as well as desktop which was important for me since I switch between devices constantly. Live betting odds update without lag and the casino side has decent variety of slots and live dealer tables. Been using it regularly for about five months now and haven't had major technical issues that made me want to switch elsewhere
