Martin-Coupal thanks for confirming this is an issue as well. At least I am not crazy. I thought that maybe adding permissions to the term store might have helped but to no avail. Per this article. https://www.spguides.com/term-store-sharepoint/

It would be great if Microsoft would respond to the thread

Thanks for the reply

IvanCole-dxcecl I did some tests and found out it was related to an access issue. However, there was no change made to the 3 tenants I found the issue, so I'm 100% it is related to a change they made. I have one tenant that do not have the issue....

Note: If it was related to a permission issue on the termstore, it would not be working when using the standard (legacy) picker....

The call creating the issue is the following:

https://mytenant.sharepoint.com/sites/demo-dept-finances/_api/v2.1/termStore/termGroups/xxxxxxx/termSets/xxxxxxx/getLegacyChildren()?$top=50

It returns:

{"error": {"code": "accessDenied","message": "End point cannot be called by the current user"}}

If I change the rest call to this, it will return all terms successfully:

https://mytenant.sharepoint.com/sites/demo-dept-finances/_api/v2.1/termStore/termGroups/xxxxxxx/termSets/xxxxxxx/Children()?$top=50

I've created a MS ticket.
