I'm testing out some of the Cloud-specific functions in my SP Cloud account and am encountering a problem with the Word Online function. We have enabled Azure AD SSO successfully but don't suspect it's part of the problem, however, thought it worth mentioning.

Basically when I click Edit in Word Online in the Document Viewer it starts to open Word Online, provides me a Word Online-looking prompt to login to Office 365 so I click Login with a Work or School Account. It seems to perform an SSO login at that point because it refreshes the page without requiring me to type anything in. This is where it gets stuck in a loop. Laserfiche Cloud shows "Loading..." the the page refreshes to the Word Online logo for 1-2 seconds then refreshes back to "Loading..." and keeps cycling between these two screens. The URL doesn't seem to change at all but it remains stuck here.

Anyone else run into this?

EDIT: I tried with Excel Online with a brand new document and I does basically the same thing. I attached screenshots of that "cycle". "Loading.." then the grey initial loading screen of Excel Online then back to "Loading." The URL doesn't change between these screens as you can see.
