Hard part is not knowing if it’s because of you reaching the maximum amount of views for the campaigns in your area or what else might be happening.
Nah, doubt it’s a problem. Btw, only Brave knows how to read the logs. They don’t want to teach anyone what it all means. But what you’re seeing there is kind of common from what I’ve seen.
One of your best options might be to just submit a Support Ticket so someone from Brave can look into with you.
Beyond that, I guess can also check out my FAQ if you hadn’t seen it, just in case anything helpful there.
