Sure. Very simple - I set a Webmeeting through user's (windows) webclient and send invitations. Attendees on desktops get the invitation and can open the webmeeting link on browsers and all is working perfect, however those on mobiles (tested that myself on several Android devices), with webmeeting app installed (Ver. 9.2.0.5) - push the right link - the app opens, seems like it tries to connect and within second or two is back to the main screen of the app (3CX logo with the blue "Log in") and NOTHING happens. Didn't tried on IOS myself but at least one attendee who tried reported failure as well.
I also tried invitation from a different 3CX instlation - the same behavior.
