Are there any recommended browser settings for MetaShare?
After having authenticated to MetaShare, MetaShare will do things in SharePoint, on behalf of the logged in user. In order to this, without any issues, it is recommended that both of these domains are added to the same security zones, preferably the Internet zone.
- https://[your tenant's name].sharepoint.com
If "app.metashare.com" or "login.microsoftonline.com" are explicitly added to the "Local Intranet" or the "Trusted sites" security zones they should both be in the same zone or one in the "Local Intranet" zone and the other in the "Trusted sites" zone.
