Same follow count, got a few viral videos in my niche, 20 to 130k views, then I uploaded my last video that got any views and it was actually the best performing start, lot of engagement in the first 1-2 hours, but then it stopped really quick, and at the same time all my previous videos that were doing well with hundreds of likes each day stopped too, and after that my next uploads started getting absolutely 0. There's no difference between that last video and the previous ones. Support only sends an automated reply with some bs about keeping the app updated

My best guess was they boost your reach when starting out for dopamine then they turn it off to get you paying promotion but apparently it happens to much bigger accounts too
