Since 2020 I often attend online conferences. I have noticed that one problem arises again and again.
Let us suppose, that a person wants to share his presentation. In order to do it in slide show mode, he should chose "share entire screen" option. But usually people chose to share only powerpoint window. It would be OK, but when the person presses F5 to start slide show, the audience does not see it. They see only ppt work area, but not the slideshow. 
It causes confusion at the conference, and the speaker looses his temper.

It would be great, if when the person choses to share only ppt window, the slideshow would work correctly.

When running hybrid meetings with a live speaker, sometimes the internet drops, is there a way to have participants muted on entry but the host not, as at present we are muted if we leave and return and sometimes don't notice straight away as we are trying to not disrupt the talk in the hall.

I was running the fourth session of a recurring meeting, and 2 of my regular participants weren't able to join (other regulars had joined fine a few minutes before). I have a waiting room enabled for the meeting, and those who made it in showed up and I let them in as usual. Later, I found emails from the two who didn't get in, saying they had tried to join and it had sat at the 'host will let you in soon' screen. I, however, never got a notification that they were waiting, so wasn't able to let them in. They did request to join about a minute after the meeting started, but I people have joined late before with no issues at all, and I certainly don't stop people joining late. As far as I know, I hadn't done anything different this week to previous weeks, when I had no issues. Is there a) a way to stop this happening again, and b) a way to get people in to the meeting even if I can't see their request to join? Many thanks!

I have been hosting meetings regularly, the last one was last Thursday, but yesterday, upon launching, instead of the regular screen with controls, I got a blank screen with only my ID and no controls (see screen capture). Attendees joined (in another screen) I could see them and hear them but I could not join my own meeting. I closed the meeting for everyone, created another meeting, same thing. I had to cancel the meeting. I have been testing creating meetings and launching, and still the same blank screen with no controls. I have updated to the latest Zoom Client 5.13.10 - nothing changes.

I submitted a ticket to Zoom support yesterday, no reply. And I have another meeting planned for tomorrow Thursday. Any ideas, solutions? Many thanks.
