Hi Jim5EF7,

Thank you for reaching out, and sorry for the trouble caused.

Could you please share more information on the issue you are experiencing with the application? Do you get any error message when trying to combine the PDFs? 

You may refer to the information on combining files in the Acrobat mobile application here: Combine files.

If you wish to cancel your subscription and request a refund, please refer to the steps outlined in the following community-featured post: How to cancel Acrobat Mobile or Scan premium subscriptions.

Let us know if you need any help or have questions.

Thanks,

For confidential documents, i rather use Adobe. I finally found later iPhone shortcut merge what Adobe cannot (mobile or Web versions). I suspect hardware speed because I cannot afford recent iPhone nor  5G or more than 1GB
