We have been having a lot of problems with Meetings and screen sharing. Sometimes it works fine but very often the presenter's screen pops back to the sharing menu after screen sharing with others connected to the meeting. RingCentral confirmed our network is setup correctly and we have ruled out our ISP as being the problem. Is this normal for the presenter to occasionally lose their screen sharing? We are using the Meetings app v. 6.0.59781.0124 (most current I believe).
