Our IT staff recently installed ArcGIS for Teams in our org's Teams environment. However, it (ArcGIS Maps user) keeps posting welcome reminders about its existence in our GIS Team's General channel over and over, sometimes many posts per day (see attached example). Are there any settings or controls to stop these reminders? I'm trying to find out info so I can advise our IT staff. I opened an Esri case about this, but apparently there's no official support for the product so they referred me to post here hoping Esri staff or others may reply? Thanks for any help.
