Dropbox and opening files in Word Office 365 - I get a white box and no ability to authorise

So this is driving me crazy 🙂

 

Running Ipads using JamF and Securly.

 

Just recently some users not all are unable to open Word / Exel etc documents from dropbox ipad application (latest version running on IOS 17.3

 

Dropbox for Teams / Office 365 for Faculty A1 licenses - I've cleaned a new Ipad and replicated and happens for me, tried on my personal ipad and can get it to sync.

 

So what happens is - 

 

Go to dropbox - open a .doc file and have ability to open in Word ( logged into Dropbox App / logged into Msoft O365)

 

Click open in Word and it goes to O365 app, white box opens (authorisation box) and this just stays blank with a connecting label at the top.

 

Go to connect Cloud storage in O365 and same thing, no authorisation just a white box. (go to other storage devices Box etc and all ok)

 

Totally confused as to where the error lies, not all users. 

 

Reviewed all settings in Jamf every user on same profile, cleaned up a ipad as stated.

 

Any advice ?
