Thank you for your reply
I have about 100 small files on Acrobat.Com which I uploaded and used about a year ago. I could Access them on my iPad with no problem.
I used Acrobat reader V1 on my laptop to upload them.
They are still accessible on Acrobat reader V1 on the laptop but not on Acrobat.com on either the laptop or the iPad.
I do not have a Creative Cloud subscription.
I uploaded a file from my iPad two days ago and this is the only one which appears on Acrobat. Com using Acrobat reader on the iPad.
