I get a message, I go to answer it - and there is a pop-up telling me about “Content Assistant in the Inbox!” - but I cannot remove the pop-up there is no way to close it down, and then answer the message.
I have refreshed and tried both firefox and chrome, without any luck… ?
I had the same problem.
This worked for me:
Under Settings > Content Assistant (very close to the end of the list in the left sidebar), you can switch the content assistant off. These settings will apply to everyone using content assistant in your account.
However, mine was switched off. I switched it on, and then went to my inbox again. Now, bottom right was a button (previously missing)
that said “Got it”. I clicked on that and the popup disappeared.
Hope this helps.
