I’ve been running into the same issue.
I use Bovada mainly for their search function which is better than all of the other books. Especially useful when playing sports like Esports or soccer games where you have to navigate to the right league to find the match. Find it in Bovada, see the league that the match appears in and then go find it in other books to line shop. I wish other books had a good search.. Heritage isn’t bad but DK, FD, Pointsbet, MGM, Bookmaker are all lacking.
