I submitted documents for a flight to MLA - dPLF and both Covid vaccinations. I've just got the email back (after waiting all day) saying I couldn't be verified, but the site doesn't make it very clear why. Is it because I didn't attached the health form (with the boxes you add letters in)?

I have also completed veriFly, got the green tick and received mobile boarding pass from OLCI - should I worry about not being verified in the BA site?
