Amazon Seller app encountered a problem (CS12)

Whilst setting up my Amazon FBA account on the sellers app, I have uploaded my passport, driver license and connected my bank account. It then directed me to a page that wanted the information again on my desktop. When I check the sellersapp it says “registration pending” and “registration pending”.

If I try to select it says Amazon Seller app encountered a problem (CS12)
Any advice?

Should I assume it’s being reviewed?
