Spanning has identified a change in the Microsoft API which affects backup of attachments stored on the Microsoft Teams Private channels.

Question

We are using Kaseya's Spanning backup product.

It is returning the following error:
Spanning has identified a change in the Microsoft API which affects backup of attachments stored on the Microsoft Teams Private channels. It only affects private channels attachments. While Spanning is looking for alternative approaches to back up attachments on the private channels here is the KB with the suggested workaround.

Microsoft has said that this is a problem that Kaseya needs to fix.
Kaseya has said that Microsoft made a change in the Graph API and Microsoft will need to fix this.

Kaseya has a recommended make a Private Team as the replacement of the Private Channel.

Does anyone have any further insight on this?
Does anyone know a vendor that does not have this problem?

Thanks for any information.
