Randomly stopped working on one of my accounts, so I've spent two solid weeks troubleshooting on my own and sending bug reports to Instagram. I've gotten no reply. I've reinstalled the app, signed out and signed back in again, cleared the cache, tried different filetypes, updated it twice, and still nothing works. Really wish I could get some help, but I guess I'll just have to jump ship to TikTok at this rate if I want to keep posting content to grow my YT channel.
