If you look at the updated guide for PIP claims and Reviews (p 129) onwards it explains the difference between the AR1 and AR2 Review forms. Most people will receive the AR1 form.
"The AR2 form is being issued from August 2023 to claimants who have: • very stable needs which are unlikely to change over time; or • high level needs which will either stay the same or get worse; or • a planned award review date due on or at State Pension age"
