When switching back from a Business/Creator to Personal account, the interface for professionals still exists

I switched from a private, personal account to a professional account after someone told me that it would give me the feature to put music in your bio. Nothing changed, so I tried switching back to a personal account.

While I was able to switch my account type back to a personal account and go back to private, the interface remains the same as a business account. My profile still has the "Professional dashboard" tab and the steps for professional accounts. My messages tab is also completely different now, being split into Primary/General/Requests.

When I access Instagram on a computer, accessing the Professional dashboard just gives me an error screen. So, I'm assuming that, while Instagram thinks I'm a personal and private account, it doesn't change the interface back to that of a personal account.

I just want my Instagram to go back to how it was before; all this other stuff is messing with how I use the app.

If anyone has a fix, please let me know. At this point I'm pretty sure I've done all I can, and I just have to wait for Instagram to fix this. Which will probably take ages or just never happen...
