I have checked your Adobe account linked with the Adobe ID you are using on this community, and I am unable to find any Acrobat Premium subscription. I can only see an active Acrobat Pro Subscription.

Thanks Amal!
@Marie Love If you have Acrobat Pro, it includes Acrobat Reader for Mobile Premium and you do not need a separate subscription.
From Adobe Help:
Can I upgrade or downgrade my existing subscriptions?
If you have an existing subscription to Acrobat PDF Pack, Acrobat Standard, Acrobat Pro, or Acrobat for Enterprise, you can access premium mobile features as well. With subscription to Acrobat Export PDF, you’ll only have access to the Export PDF tool on mobile.
