There’s an updated (January 2020) Dynamics 365 Mixed Reality Licensing Guide. There’s information added on page 5 to clarify which Remote Assist users need to be licensed with Teams: the Expert giving assistance DOES need a licence, but the user being assisted DOES NOT. There’s also a new section and Appendix added detailing Dynamics 365 Support Plans and policies, and you’ll find these on pages 8/9 and 10. Grab this guide here (http://bit.ly/MixRealLGJan2020) to keep your Licensing Guide collection up-to-date.
