Have had problems with this app since downloading it. I have uninstalled and reinstalled, updated, tried using web suggestions to fix, and nothing has worked. I don't get any notifications to my phone, so I have to go into the app to see if I have any messages/likes/comments. I don't have the option to add playlists. And I have tried to contact TikTok to get this resolved multiple times, and they don't help or simply don't respond.
