I am experiencing scaling issues. I have one low-budget campaign that runs from 12 AM to 5 PM with a daily budget ranging from $30 to $60, solely to warm up the RPC. During this time, RPC is very low, but the CPA is also low, allowing me to generate profits consistently, even if I run it 24/7 across all 20 verticals. However, the peak time for high RPC is from 8 AM to 5 PM. In these hours, I run a campaign with 20+ ad sets, each set at $20, featuring a very small CPC of $0.3-$0.5. however doesn't matter if my CPC is low my CPA increases significantly, going from 0.4-0.5 to 1 or 1.2. Consequently, I'm observing minimal profits on some verticals and, in some cases, even losses.
