After Tiktok got banned I can't send messages

Idk if this is the channel to ask this but does anyone know what to do? I'm from the US, and after the ban and unban of Tiktok I've had to access Tiktok through my computer because I deleted it off my phone, but it isn't letting me send messages or videos to my friends so I have no way to continue my streaks. Does anyone know how to fix this?
