OD4B | New look replaced by Classic Look

[Martin Braley]

Is anyone else experiencing an issue with their OD4B only displaying in 'Classic Look'?

Our users are complaining that their files are displaying in list view only and not the new UI. At an admin side, our team haven't made any change while at a user perspective, the option to change over to the new look isn't available.

Possible the setting in SharePoint Settings was switched back to Classic View? In the O365 Admin Panel.

Mmm...I'm not so sure this setting also affect ODFB and Group Files, but I agree with @Kevin that it's the first thing you should check.
