Have Zoom basic and downloaded latest update (earlier ones do the same). Have T-Mobil Home Internet through cell tower, and wireless from modem to my computer. When in Zoom meeting today with 41 participants (same happens often in other meetings with more than 3),  experienced  several breaks/pauses/buffering episodes during the first hour (12-1pm Eastern),  about 10-15 seconds long with missed dialog. During last hour of meeting, had no lapses. Did speed test when it was occurring. 30MbPS download, and 11 upload. Have worked with T-Mobile several times and they can find no problems and have no resolutions. We stream television through the same wireless connection, and have very, very few buffering lapses, mainly only during bad storms. Can you suggest any resolutions to this problem?  An aside: T-Mobile main servers are in the Detroit, Michigan area, about 300 or so miles away.

For a better user experience, I use an external HD webcam clipped to monitor located a bit more than 3 feet away from my head.   However, my video image fills only a tiny portion of the Zoom video area.   Is there a Video Advanced setting that would allow me to "zoom in" closer, so that my head shot occupies more of the frame?  I'm always the smallest appearing participant in meetings but can't find a setting to adjust my image size relative to the video area.

iPad vol ok when playing YouTube videos & music so it’s not the iPad speakers.   Since I can hear faint voices, the microphone isn’t muted.  Various zoom articles said to click on the up arrow near the microphone icon, but there isn’t an up arrow near the microphone.  I have the latest Zoom version on my iPad.

I tried to change the date on my recurring series of meetings in order to keep the same meeting ID, but when I did the meeting from today forward simply disappeared. When I went to the previous meeting, the meeting ID was missing from the settings. What do I do to salvage my recurring series?
