Thanks for your post. What a great question you have asked. Unfortunately, I don't have any personal experience with appealing PIP. Hopefully, someone else with personal experience with appealing PIP can respond to you soon as I know you are looking to hear people's lived experiences with this.
In the meantime though, I have heard of successful cases. Disability Rights UK published an article about the success rates of appealing PIP in 2019. If you are interested in exploring this further, you can find it at https://www.disabilityrightsuk.org/news/2019/september/pip-and-esa-appeal-success-rate-now-75-cent.
I hope this helps! If you have any other questions or want to discuss this further with us, please don't hesitate. We are here for you and we are listening
