stuck at 72% for esign

I'm experiencing the exact same issue with Adobe Acrobat freezing at 72% when preparing a document for e-signatures.

My Adobe account clearly shows that I have 1 free Request Signatures transaction remaining, but the upload consistently freezes at 72%.

I've tried multiple PDFs, including a simple one-page document, signing out and back in, and repairing Acrobat. None of these resolved the issue.

Interestingly, when I select "More Options", I can get past the 72% upload screen, but Adobe then displays an error saying I don't have sufficient transactions available.

To isolate the issue, I signed out and switched to my second Adobe account on the exact same computer. That account showed 2 free transactions available, and I was able to successfully prepare and send the exact same document for signature without any problems.

This strongly suggests the issue is specific to my original Adobe account rather than the document, software, or internet connection.

Could an Adobe representative please investigate why my account shows an available free signature transaction but refuses to process it?

I'm happy to provide my account information privately if needed.
