Is there a real way to stop zoom from turning the volume up when entering a meeting?

Disabling the "Automatically adjust microphone volume" box does noting, all things are exactly the same with that box checked, or not.

This is a very inconvenient little bit of control zoom holds, please guide me

I must coach some folks on muting and un-muting with the usual icon on all platforms. Also for push to talk but only on recent laptop or desktop. A frequent ambient-noise offender uses a spouse's iPad. Can one who is self-muted push to talk via either a tablet's touch-screen keypad or a connected physical keyboard?

My zoom keeps freezing.  I've uninstalled and reinstalled.  I've had a computer tuneup to fix any possible corruptions.  Still the same issue.   Just random "not responding".  Before meetings.  Signing in. During meetings.  Etc...  Anyone experience this?  I'm windows 10

This morning, I recorded a Zoom meeting locally.  The initial recording was interrupted, so I stopped recording.  Then, I began a 2nd local recording.  When I closed the meeting, I received a "recording failed to convert" message.  I am now only able to find the initial, interrupted meeting recording in the remote default folder on my computer.  I was able to convert this file manually.

My Zoom version is 6.0.2.  The Zoom session included a shared video in a split screen with a deaf interpreter.  Is there a reason that the 2nd recording would not be in the default folder? 

I did find a cloud recording that includes only the shared video.  Though I was sure that I used the record to this computer button, is it possible I accidentally record to the cloud?  If so, I don't understand why I would have received the failed to convert message when I closed the meeting.

One of my students is having a problem when I screenshare.  I'm sharing a slide set and one student's screen is not getting refreshed.  His view is about 4 or 5 slides back.  After a long period of time (10 - 15 minutes), his screen view finally catches up.  He is using an iPhone 7 and he said that he doesn't update his OS all the time because it has caused problems in the past.  I would imagine if I stopped sharing and reshared, that it might fix it for him, but I don't want to have to do this after each slide.  Any ideas?
