The Biggest Challenge in using MS Teams, and after reading most of the comments, is the networking and the IT support for the users. In my Opinion i believe that to solve this issue , the resource Centers must be used as a hub for the trainers to implement their training. The presence of the IT support with the trainers and the internet connection suitable for the big load of materials used is helpful in making the Training a successful experience and not a burden on the trainers and the trainees.
