UK Immigration Identity Check App

Hello,

Has anyone used the UK Immigration ID Check application recently?
My application was approved and I got the entry clearance vintage on my passport with 90 days validity starts after 15 april 2025. In the approval email I was instructred to create a user at UKVI to view the details of my eVisa online.
I created a user, connected my smartphone to my account, but I couldn’t verify my Identity. Everytime I try to take a photo for the passport page I get this error (There is a problem with your document)

In the application there is a phone numebr for support, I tried to contant them many time with no luck, and I didn’t find the support email.

Is it mandatory to have the evisa linked to my account prior travel to UK? or I can enter UK using the entry clearance vintage on my passport?

Thanks
