Linux Mint (latest version) Zoom (latest version) is installed.
The existing background images can be selected and work without problems.

How can standalone background images be added?

Via the button "plus" (see picture) this unfortunately does not work under Linux.

I have two meetings I join regularly. Each is setup in my browser as a bookmark including a coded password so I can join the meetings with a simple click. The browser invokes the Zoom application and the meetings should start. But only one of them starts properly.

Meeting A shows a video preview before I join, the starts with video and audio enabled and everything works as expected. Meeting B did that until about two weeks ago. Now meeting B does not show a video preview, only a black box. When started, both audio and video are disabled and cannot be enabled. I can see and hear others but all they see for me is a blank box.

When I try to unmute, I get a message, "The host is not allowing participates to unmute themselves." But the host has not done that. If he tries to manually unmute me, I get a popup asking for my agreement, but when I agree, nothing happens. If I try to enable video, there is no response.

Since this works properly for meeting A, I presume there is something unique about meeting B, not something wrong with my installation, but I can't guess what that could be. Meeting B works properly for all other participants. Can anyone suggest what could be wrong?

My system is running Fedora Linux 39, fully updated, and Zoom 5.17.5. I've also tried downgrading to Zoom 5.17.1 without any change in behavior. Starting directly from the Zoom app instead of using a browser link doesn't change anything. I've also tried running with both X11 and Wayland environments.

I teach with Zoom.
If I have multiple screens open and minimize my participants screen to reference other materials, it is very hard to find them again. Often I have to waste time minimize other screens and search for the tiny black box containing the minimize/maximize buttons.

Similarly, I waste time searching for the control panel even though I have "Show Control Panel" checked. Again--minimizing screens and hovering blindly until it appears. It makes the process inefficient and a little stressful. 
Is there a way that the participant screen could be linked to the control panel such that (a) the control panel is always visible, (b) participants can be minimized/maximized from the control panel, and/or (c) the meeting can be linked in the toolbar at the bottom of the computer screen as a static reference? 
Thank you. 

Hello! I have already recorded some of my classes on Zoom to the cloud, and have shared the recordings with my students. One student asked if I could provide her with a link that has closed captioning because she's hard of hearing. IS there a way I can provide this for her, even though the class has already been recorded and saved to the cloud?

I run reports from polls that I have been completed during training.

Some of these download fine and others fail to generate.

Does anyone know why this might be?

The process is:   Account Management, Reportings, Meeting , Poll Report.  I then choose the dates.  This brings up the list of trainings completed during that period.  Some generate fine and I am able to download the report.  Others have the name and download greyed out and I am not able to download the report.

Something is blocking me from scheduling a meeting. I set it up and hit save and get the message "Something went wrong. Please reload this page."  I have tried multiple times on Chrome and Edge browsers. I have turned off Windows Defender Firewall to see if I had changed something there. Have never had an issue prior to this. Works fine on my desktop at the office. Only is happening on my home computer.  Certainly a software issue. Ideas?
