@vaporhunter Just tested this: you can still switch from a business account back to a personal profile by following these steps—Profile > Menu (three bars) > Settings > Account > Switch account type > Switch to Personal Account. If you don’t see the option, try updating the app or checking under “Account type and tools.”
Also, if you ever need to view Instagram Stories, Highlights, private profiles, or save content anonymously, Picnob is your best bet.
