Ok, this is kind of embarrassing.
Happens that with MS Edge I cant see the O365 Group I have activated for a Record/Entity.
With Mozilla, all good. But with Edge, nope.
I got a message requiring me to sign in, and then it opens a different window of the browser and before I can do anything, that same window ask me to leave it and close it automatically.
Cuek!
Happy to hear any comments.
Cheers.
