Microsoft Forms keeps looping back to sign on screen after entering in a valid account email

[dbstones]

Hi All,

Not sure if anyone else is experiencing this. But trying to sign into forms with a valid (admin) account email and loops back to enter email again does not go past this screen. Have tried logging out, clearing cache, and different browsers but the same thing occurs on all screens.

Extremely weird and frustrating. Any further guidance is appreciated. 

BTW when the hell is microsoft going to allow external sharing for file uploads!!!!!!!!!!! Another frustrating speedhump. Google and others allow it why not microsoft.

@dbstones Yes same here, several/all other office 365 apps work (at least the ones i usually use) but when loggin into forms, on macbook, the login screen goes epileptic...
It does work on a windows PC... so a mac problem here...
