Problem with OneDrive-Docusign

Hello,

I have been using Microsoft 365 Family with Word Online and OneDrive for a long time, and the "Request Signature" feature worked perfectly until recently.

Now, every time I click Request Signature, I receive the following error:

"We couldn't connect to the '{0}' catalog server for this add-in."

I found your announcement about the retirement of the Legacy DocuSign for SharePoint integration, and I'm trying to determine whether this is the cause of the issue.

My questions are:

Is Microsoft 365 Family still supported for the Request Signature feature in Word Online?

Do I need to migrate to Microsoft 365 Business to continue using this feature?

If so, which Microsoft 365 Business plan do you recommend, and will my current DocuSign account continue to work after the migration?

I have already cleared my browser cache, signed out and back in, and tested different browsers, but the issue persists.

Thank you for your assistance.
