Thank you.
The thing is that I've already been at Step 4 "Qualification Approved". On the Information page there was this button to proceed - upload actual documents and update address info, etc. So I did and submitted, and application moved to Step 5 (I guess). But now I have this strange "Return Pre approved" status which I don't recognize in the schema ))) So it worries me. Maybe it's OK ????♂️
Regarding notifications etc. - yeah, it's kinda not obvious. E.g., when I got my "Qualification Approved" status, I didn't get any emails from BoI - I just saw it in account )) In the Notifications area I still have only endorsement from 20th March.
