PIP MR - No reasons given in Notice letter

Hello. Following a telephone assessment I was not awarded PIP. I received 6 points for daily living and 4 points for mobility. Using your guides, I submitted a Mandatory Reconsideration request and provided new medical evidence. My MR submission detailed the main factual errors and omissions in my assessment report (there were lots but I focussed on the most significant) and I explained why I believe I meet the criteria for PIP. I'd already submitted lots of medical evidence along with a detailed PIP2 assessment form, having used the guides. I received my mandatory reconsideration notice today. No change to previous points. In the 'how I made my decision ' section other letter gives a generic explanation of how PIP works but says nothing at all which is specific to me and my application. It doesn't acknowledge or respond at all to the info I gave for in the MR submission or my new medical evidence. Please could you tell me if this this normal? I feel stuck. Because they haven't explained why my MR info and evidence hasn't changed their decision, I don't know what to argue if I appeal. I'm not sure they even looked at my MR submission. As you advise in the guides, I did the MR in writing precisely so I could set everything out clearly so nothing could be overlooked.
My second question is, if I appeal, will the Tribunal automatically receive all the information I've previously provided to DWP (pip2 form, medical evidence, MR submission letter) or do I need to supply evidence again from scratch?
Thank you in advance for your help.

Thank you for your reply.

Shouldn't the mandatory reconsideration notice give reasons why the reconsideration wasn't successful?

Thanks very much for the great advice, really helpful.
