Any important changes in PIP appeals since 2019?

Hello, I’m preparing a PIP appeal for my son , 26 . He is autistic, has severe anxiety and also widespread chronic pain from Joint Hypermobility Syndrome. He was on HR care and LR mobility and he was awarded 0 points following a review over the phone. In 2019 his PIP payments were stopped and then reinstated. This happened after his appeal was submitted but before the tribunal. Very little has changed in his conditions since 2019, so my plan is to use an updated version of that appeal, which I created using guides and info from this site. I wondered if there have been any major changes I should be aware of . The points he received all related to autism and anxiety: preparing food, taking nutrition, managing therapy, washing/bathing, dressing and engaging socially. For mobility he qualified under planning and following journeys. The main thing that is different this time round is that the review was over the phone rather than face to face and that I was not able to be there to support him. The call was recorded and he answered some questions in a way that gave the impression he has fewer problems than he actually does. This is partly due to his extreme discomfort with social interaction and wish to end it asap. He also tends to not be the best judge of his own abilities and overestimates what he can do in real life rather than theory. So I will add that in as I anticipate parts of the call will be used against him. Any pointers gratefully received.

Thank you - I wasn’t sure about using specific examples , of which I have many . So it’s good to know that it should be useful
