Hi @Jose Miguel26896971wwpk,
Hope you are doing well. Sorry for your experience with the Acrobat Reader Mobile subscription.
Would you mind trying the below troubleshooting steps and checking if it helps:
1. Open Acrobat Reader Mobile.
2. Click on your profile icon-> Subscription.
3. Click on the blue icon saying, "Restore Purchases."
If this does not help, please share a screenshot of the message you receive when trying the steps.
You may take further reference from here: Manage subscriptions — Acrobat for iOS Help.
Hope this helps.
