Merging PDF's new problem

Hello Kathm,

We apologize for the inconvenience caused, as per the description above, you are not able to upload a PDF file using the Document Cloud service as getting the error message that another instance/operation is in the process, Is that correct?

The record shows that you are subscribed to Acrobat Pro DC subscription with your current Adobe ID, try uploading the file through the URL https://cloud.acrobat.com/  on a different browser like Chrome, or Firefox, or Safari and see if this brings any difference.

If you are getting the message while using the Acrobat Pro DC, please sign out from Acrobat, reboot the machine and sign back in and check for any pending updates of Acrobat Pro DC from help>check for updates. Reboot the machine after installing the updates and try combining the PDF files.

If the issue still persists, please share the following details:

• Dot version of Acrobat Pro DC installed, to identify refer to Identify the product and its version for Acrobat and Reader DC
• Is it a Mac or Windows machine?
• Are you trying to combine the PDF files online with the URL https://cloud.acrobat.com/combinepdf  or using the Acrobat Pro DC?
• Is it specific to one/two PDF files or with all the PDF files?

Let us know how it goes and share your findings.

Regards,

Anand Sri.
