Excel 365 - Not responding and Ghost typing

[Max_Power]

Just wondered if anyone else is having issues with Excel 365 (app and online version), causing massive issues here today for everyone in school. All 1:1 devices, and workstations have the exact same issue when working with either a blank Excel sheet or a previously saved sheet (in OneDrive or SharePoint).

 

Opening Excel you get around a 2 minute hang or a not responding greyed out screen, and then once it does start responding you type something in a cell, and it appears a good 20seconds later or goes into a not responding state again?

 

We can replicate the issue with any user on any device - started getting the issue yesterday but its continued into today?

 

Saw this on the service status but not sure if its inline with the issue we are seeing or not?

Users can't access Excel files in Microsoft 365 services
