PIP - awarded enhanced, but do I still challenge?

Your helpful advice would be very welcome.

My daughter (16) was awarded enhanced for both the care and mobility elements of PIP scoring 12 points on each (minimum required).  We are relieved and feel she deserves the enhanced judgement.

However, there were some decisions that were nonsensical.  I.e. she was awarded 0/12 for communication. She is autistic! Communication is THE ISSUE she struggles with!

I don't know what to do now.  Do I ask them to reconsider or just leave it?  My worry is that if I leave it, what happens when they review it in 3 years time and they give her the same again and I didn't challenge it this time?  If I challenge it, could they downgrade her on other elements and downgrade her from the enhanced rate?

Do I just write to them to lodge that we do not agree with some aspects of the decision but accept the overall outcome.

Thank you for reading.
