I have a new Dell laptop and just installed zoom. (Zoom would never work on my lenovo). However, the integrated camera does not turn on. The white light turns on as if the camera was working, but there is no actual video, only a camera with a line through it. When I go to the settings, the only camera option it gives me is "USB Camer". I have no idea why and i obviously don't have a camera connected through a USB. I tried restarting. My settings already give permission to access camera. What else can i do?

I have my kids' Chromebooks set up to only allow approved sites. When they try to join a zoom meeting, they are getting a reCAPTCHA error. ("You failed the reCAPTCHA verification") If I change the setting to allow all sites, they can join. I've tried on two different devices with 2 different google accounts. Is there a site I can allow that will enable reCAPTCHA validation without removing the filtering I have set up on google Family Link?  This was not an issue last spring; we just encountered it at the beginning of this school year. 

I have implemented https://github.com/zoom/meetingsdk-web-sample for meeting. This is working fine but after join meeting if joining from this custom created application then not able to see full screen option and video screen is showing small also facing issue with video quality.

How to fix this issue?

I have a process where I need to copy the text from the AI generated smart chapter text and paste it into a document. I have never had a problem until this week. 

Step one - I go to the first smart chapter, select it and then move the cursor down to where the summary is displayed below it and copy and paste it into my document. 
Step two - I try to do the same thing for chapter 2. I select it and the text I need to copy is displayed, however, if I move my cursor off of the chapter so I can select the text I need to copy, it instantly reverts back to the text from the first chapter. 

Thanks in advance for any help! 

Hardware is Dell Optiplex 990 desktop with  i5-2400 3.10GHz 8GB Ram 500G HDD Windows 10 64-bit
speakers are small  external with standard   3.5 mm wired connection connected to audio out port. Realtek High Definition Audio drivers.

 Zoom meetings are the only application where the volume is extremely low. Zoom volume setting and windows 10 volume setting  are up at maximum and I can barely hear.  For all other applications,  playing videos, etc. the volume from the speakers is extremely loud. There must be a Zoom setting or option that I am missing.  Please advise, thank you!
