Sharepoint Lists - cannot add to MS-Teams tab from other separate sites
I am not able to add a list from a separate Communications Site to a Teams tab although I am owner of everything with full control. The error returned is "That link did not work because you either do not have access or it is unsupported.".
Lists created in the MS-Teams linked Sharepoint work, even when using the URL method of adding to create a tab.
I have ensured that the site collection features of the Communications Site match those of a teams linked Sharepoint, but to no avail.
This is a major deficiency and thwarting the benefits of working with ShP lists in MS-Teams
