unable to access gmail which is covered by a google banner at login
MacBook with OS 10.10.5.
This computer is being used in France, and dialogue is in French.
We have lost access to gmail. At login, the inbox appears for 2-3 seconds and is then covered by a document which has a banner which states:
"Gagnez en productivité graçe au fonctionalités intelligentes dans Google workspace"
We are unable to remove the document having spent several hours trying to do so, thus we are unable to access emails. Surfing the net is no problem
HELP!!!
Regards,
Nigel
