What am I wrong about? 300 views is the maximum each time.

I have a similar problem, and moreover, second/third/next videos don't get any views at all. I am using an iPhone + VPN (nordvpn/purevpn/surfshark) + US sim card + correct device setup parameters (locale + timezone + icloud config). Some other people I see working with tiktok seem to have problems launching new accounts too
