Ability to disable private viewing by defualt
It should be possible within Meeting Settings to disable private viewing (the ability for meeting participants to scroll through PowerPoints on their own) by default, without having to disable it manually in each meeting.
+1 for this
When this setting is enabled (the default) external users connecting by a CVI / video gateway cannot see a PowerPoint presentation after the 2nd slide. Big issue when attempting to provide a sales or training PowerPoint to non MS Teams participants.
