Clarity on what is included with photography plan

Hi
ive just subscribed to the photography plan, downloaded and signed into Lightroom on iPad. I was assuming that my £9.something a month payment covered all its functions but I keep getting prompted to freetrial or pay an extra £4 odd a month for 'premium' features such as importing and editing RAW files, using retouch tool...  I had assumed my subscription would cover these features, which seem pretty basic expectations to be honest. Am I missing something or have I basically paid a monthly fee for storage and the apps are just the free versions? Thanks in advance
