I had the exact same problem, everything looked normal on my end but no payout for 3 months. I was flagged even though it didn’t give me the message saying so and I was seeing ads as normal. It took a lot of complaining here and on twitter, and working with one of their engineers to verify that I wasn’t trying to abuse the system. but I was eventually unflagged and received rewards properly this month.
If you have the will to continue you could try reaching out to bravesupport on twitter with your ticket #. I had better luck getting responses that way.
