Since this new design, 100% of my calls have turned into an absurd process of banging everyone's heads against the wall to try and make the basic 'give control' function work.
In talking with support, we went into settings and disabled the ability for people to join via the web, but that solved nothing.
The problem is that when you send a link to a client, or they join from a meeting with that link, what GoTo is pushing as the downloader is the older GoToMeeting installer (orange icon w/ white asterisk).
What your clients have to do is install the new GoTo for Windows app so that they can properly give control.
As Glenn mentioned, you as the organizer cannot request control right now, but if your attendees have installed the new correct app, the control process does work.
GoTo support says that they are still working on the program - I mean, sure, but I know I've been dealing with this control mouse/keyboard issue for at least 6 months and they need to stop including the wrong installers which is what I think has turned all of my meetings into an apology session for this program that can't work properly.
