Hi @galmind ,
We would need some information about these attendees in order to replicate their experience, as well as how you are using GoToTraining at point when you share the Timer.
Are these attendees joined through a mobile app? Web browser? Desktop app, and which operating systems?
Are you screen sharing at the time, or watching another presenter share?
If this attendee was not using the desktop software, then they will not be seeing the Timer pop-out. By the way, this feature may be 'floating' in mid-desktop on the Attendee's side, and won't automatically be attached to the control panel itself.
