[Hanson622]

We want back the Teams Private Channels site list, in which a separate Site Collection is created to keep the attachments from the Team Private Channel.

We really want back the ability to do Spanning backups for Teams/SharePoint private channels. Please allow the API for private channels to resume. 

[BLaird1]

Please update the API to include all channels, both public and private.

The /sites endpoint should return all site collections including multi-geo sites and private Teams. This should be the one place for every SharePoint site.

We desperately need this for Spanning backup!

[cmuncy]

Agreed. Not being able to get a list of all site collections and breaking existing backup solutions is really a bad look. If you have another way to get these from the graph api, please do share.

This is crazy. We need this for our Spanning Backup for this is breaking our private site's backup.

"GRAPH API is not allowing access to query private teams sites the way it used to"... Will this be addressed?

We also need this for Spanning to backup Documents in Private Channels in Microsoft Teams. Thank you.

It's really important for us too ! Please give access to private team via Graph API.  Backup is a basic protection concept that Microsoft can't ignore !
