Dropbox, OneDrive dialogue not showing

Hi, I am not seeing sync between Mac and iOS.

Attempting to use Dropbox (OneDrive would be an alternative) but I am expecting to see a dialogue to select the Dropbox account (I have 2) and probably, to authorise.

Authorised OK on the iPad but I am not seeing the expected setting option on the Mac app.

And not seeing my content…

Did you select Dropbox as a sync target (in the Config) on macOS? What happens when you click on Synchronize?

Yes Laurent, Dropbox is selected as sync target and there appears to be some action on ‘Synchronise’ and a time and date – see screen shots
