Unable to log into Instagram accounts

Hello,

I work as a digital marketing assistant and recently I have not been able to log into the IG accounts of the business we work with. I keep getting the same message even after trying multiple times, prompting the info manually, and even uninstalled and reinstalled the app.

the message i get goes:

ERROR
please wait a few minutes before you try again

Anyone had had the same issue? Or ideas on how to fix it?
