Support Group ESA to UC Migration - Incorrectly Asked To Provide Fit Notes

I didn't realise I had to have a Claimant Commitment meeting for Contributions Based New Style ESA or UC. I did read the 59 page guide. I thought because I was in the LCWRA group and out and out of the 4 Conditionality Groups I'm in "No Work Related Committments" I thought my claim would be processed entirely online.
I also informed the UC Migration Helpline prior to claiming I am severely disabled and have complex needs. I was assigned a Complex Case Coach/Manager who never called me.
I've asked UC to put a "Pinned Note" to my claim to make reasonable adjustments due to my disabilities. I've asked them to confirm they've done this - they haven't. However, I've asked them to confirm several things - they haven't. All via my journal.
A friend was in the same situation. They received CB-NSESA and UC to replace their ESA. They had a 10 minute phone call with the jobcentre and that was it done. I've informed them I am unable to attend a jobcentre. My PIP assessment back in 2017 was a home assessment.

I accepted the Claimant Commitment back on July 31st online for UC. They incorrectly asked me for Fit Notes. I complained. They retracted their request. Sorted.

I haven't had my claim formally calculated - it hasn't been 4 weeks yet. An agent at the service centre added a calculation to my journal. To replace my old legacy ESA I'm receiving a mixed award of CB-NSESA and UC.

What concerned me was the post that mentioned "a Claimant Commitment meeting". What is that meeting? I've verified my identity online. Accepted the online Claimant Commitment. Received a calculation from an advisor after 1 week in my journal that seems correct. Apart from waiting for the formal calculation around the 4 weeks mark then being paid around the 5 weeks mark isn't that it?

I didn't realise I needed a "Claimant Commitment meeting"? A friend in my situation had a 20 minute phone call in my friend's words "to explain how it works". That was my friends only "meeting". Then they got paid.
