so I tried two gambling cpa options recently, and man im stuck again. first one is the well-known big network, good payment terms but their offers seem saturated, cr keeps dropping even after a week of scaling. second is a smaller network, less volume but better cr and payout, but their support is terrible and I feel like Im leaving money on the table. tried to mix both, but nothing is sticking. anyone had success balancing these or should I just double down on one? just frustrated cause nothing seems to move the needle lately and im running out of ideas.
