I see this article (https://support.zoom.us/hc/en-us/articles/115005859366-Manually-rotating-video) for manually rotating video, but it seems to only work for desktop.

I have an iPhone that I can't physically rotate (it is locked on a stand) so I need to rotate the picture 90 degrees. But I don't see the rotate icon on the  on the iPhone app (only on desktop). How does one manually rotate video 90 degrees on the mobile app?

My blue tooth headsets work great on my computer except on zoom.  I'm working on a Mac.  When I switch to either headset a message comes up that it is switching me to the device specified but then nothing happens and I end up having to listen from my computer audio.  How do I correct this?

I was sent a copy of a zoom meeting that was sent on the cloud. I downloaded the files but cannot figure out which app will open up the zoom meeting from my files. I get a message to look for the appropriate app but have no idea what I am looking for. I want to be able to review the meeting again and take notes. I assume that once downloaded I can go in again and take notes and use the meeting as I need to. I just don't knowhow to re-open it once it has been downloaded.

A few people I have scheduled a meeting with can't access the meeting as they don't have an account. How do I get past this? 

One person was trying to sign on through the computer and got the error message they needed to sign in which they don't have an account. 

Another person was trying through their phone and got the error message sign in to join. It needed authentication on the commercial Zoom platform to join. That person had an account and was able to sign in. 

Is there a way to change my setting so you don't need an account to connect with me on zoom if I send the link to you? 

We have two laptops in our condo - both laptops are experiencing frequent screen freezes while on Zoom. What can we do? Sometimes it auto corrects and sometimes we have to go out and come back in to Zoom. What can we do to prevent this? Should we reinstall?

I’m finding that there are lots of options on the task bar that I don’t need in meetings and events. Is there a way to edit or reorder? 
typical settings would be participants, chat, polls, breakouts 

The most used and useful always seem to be past the three dots 

thank you
