Just applied today and it did appear to be straightforward. So much so I am expecting there to be a problem - because usually there is one.
Each area was split into sections which turned green once you had put the info on that it wanted.
The only issue - I didn't have two of the required evidence to prove who I am, so they are doing a phone interview.
I said preferred contact was text. So they sent me text to look at the journal that gives me the date and time of the phone call. It also gave me the info they require, back statements, (photo ID which I now have, that isn't a passport or driving licence)
It asked if I was on ESA in the support group, so hoping that's a simple swap into the lcwra of UC.
Fingers crossed the first payment is correct.
