Approximately once a month when I fire up Excel I get a grey banner message in the Formula Bar saying something along the lines of "Make that last minute adjustment ....". If I ignore the message, it reappears from time to time when I start Excel, until I click the 'Got It' button which is part of the message. I'm then taken to an IE11 window (not Edge) with details of this wonderful feature that I assume Microsoft are trying to promote. The message then goes away for another month or so. How do I stop this annoyance? I've contacted Microsoft Support but they couldn't tell me how to stop it. I know it's not a big deal, but I find it annoying that they keep nagging me like this. Thanks, Chris.
