@Declan63 Welcome to the community!
This is sometimes being experienced by some host.
I myself experience something similar to yours. I was asked to resubmit some info during my early days despite it is already submitted.
I would suggest contacting ABB support to check the real status of your account.
If there is link in the email you receive, I suggest completing it.
I ignored that on my early days and got suspended for a while.
seems like a bug on the app.
cheers!
