I have followed every step on the official help page for every device/application including the application, online, and on mobile ( https://support.zoom.us/hc/en-us/articles/8715431556621-Changing-your-name-on-Zoom#h_01GBDJXA2H4Y1FWECP374PGQEW ) but for more than a year now, every single zoom call I host or join my display name is defaulted to my legal name "Timothy" which I must have used to sign up originally for the service several years ago, instead of my entered name of "Tim". 
Is there any way I can fix this? Or is this an issue getting fixed sometime soon? It's getting really annoying having to change my name on every single call I make.

I've been saving my meetings locally to my pc. It saves in 3 parts. I sent all 3 parts to a participant and was told they couldn't see the gallery view only the host view. Is there a way to fix this?  

In order to play the zoom meeting from saved, do you need to download all 3 parts?

Thanks

ps -I'm new to this so please let me know if there is somewhere else I should have posted this

Am using a Windows 10 PC with an Intel i7 chip. I update my Zoom software regularly. A few times in the past month during a meeting I'm hosting, my video and controls freeze, although participants can still hear me. Screen sharing seems to be the trigger.  Fortunately the problem resolves itself after maybe 20-30 seconds. 

Other hosts I know have experienced the same issue since late summer. Some had to reboot their computers, since they could not exit Zoom nor did their system unfreeze. When they left the meeting,  Zoom assigned a new host and continued it, so the former host was able to rejoin after they rebooted. 

What's the fix? Is there any way to regain control of the controls when a host freeze occurs?

I had a meeting for about 4 hours. Then the size of the recorded file was so large (about 20GB). Also, when viewed with VLC on a mac, a black screen appears for 40 minutes, and for 4 hours when opened with Quick Time Player.
The video file is large, so I'm wondering if I can somehow restore it.
Does anyone have similar symptoms?

when in an iphone zoom meeting and video is off
my thumbnail picture is floating instead of flat with the others
and the screen of persons is vertical instead horizontal
