Excel Addin Tab disappearing from the Menu

Hi community,

Have you experience users reporting Excel Addin Ribbon disappearing from the Excel Menu ?

The problem behavior is: 

• User reports that OneStream Excel Add-in disappeared
• We are able to mark it as enable again
• After some time the add-in gets disabled again for the same user
• We have tried to reinstall OneStream Excel Addin, and the add-in get enabled, but it disabled itself after some time.

Users use different ERP Add-ins, it may be a compatibility issue, have you any remediation for this cases ?

Regards!
