Stream delay is probably the biggest issue with live betting imo. Even a few seconds can make a difference when the odds are moving fast. Split screen is a nice feature, but it doesnt help much if the video is already behind the market. Sometimes the odds change before you even see what happened lol.
Smaller leagues are even worse since theres barely any coverage and you're stuck watching the scoreboard anyway. Would rather have a reliable stream with a bit less features than all these extras that dont really help during live matches.
