New users with new API Tokens not working

Is there a issue with folks getting new API tokens's not being able to access the new API. I have had a few users hit me up with issues getting devices to do simple things. The ironic thing is I can do it with my setup and in some cases we have the exact same device models.

The model numbers involved that were reported if it matters are H615A, H615C, H7122, H7126, H7142
