I used to be able to right-click a document in Google Drive and open with Adobe Acrobat for Google Drive, which I have registered with my acount a while back. As of yesterday afternoon, when I try to do so, I get an endless spinning wheel.
This only affects Google Docs; if I have a PDF file in Google Drive, I can right-click and select open with Adobe Acrobat for Google Drive.
Using Google Chrome, in Google Drive, right click a Google Docs document. In the contextual menu, select "Open WIth" and then choose "Adobe Acrobat for Google Drive". Normally, this displays a vignette of the document, and then on the top right you have some options, such as to edit the document or send it for signature.
I have tried in incognito mode and it works fine. I have removed all of my Google Chrome extensions, cleared all data (cookies, browsing history, files, etc.) but to no avail.
