Invalid authentication method for recipient error when adding myself as recipient in Adobe sign using Google Drive integration

I’m trying to use the Adobe Acrobat Sign integration with Google Drive. However, when I open a document from Google Drive in Adobe Acrobat on the web, press Request E-signatures, and add my own email as recipient I get a popup with the error “Invalid authentication method for recipient “. However, other recipients work.

The Google Drive integration works great when it works but is very unstable in general. Another problem I have is that sometimes the signed pdf is placed in the drive folder of the original document as expected but sometimes it ends up in my Google Drive root folder.
