Can someone tell me the actual DNS records to use for domain name verification?

I'm trying to verify our domain name, and it seems like there's incomplete and conflicting information. The instructions in the verification popup give me a domain-level TXT record, OK that's done. Then it says it wants a CNAME to "events-branding.zoom.us," but doesn't give me a subdomain for that CNAME record. If I try to use "events-branding" as the subdomain for the CNAME record, then in the verification failure error message it says my A record was not found. But they didn't tell me to create an A record! And over in a help document, it says to create a different TXT record for a subdomain as well as an A record, but doesn't give me an IP address to point the A record to!

So, could someone who has successfully verified their domain for branding share what DNS records they created?

I have a Zoom Event set up and it has a few existing sessions and speakers.

I would like to upload the remaining sessions and speakers using an CSV file (basically using the instructions at https://support.zoom.com/hc/en/article?id=zm_kb&sysparm_article=KB0069120).

I have been completely unable to get this to work. I upload session information through CSV file as per https://support.zoom.com/hc/en/article?id=zm_kb&sysparm_article=KB0065263 but when I get to the step that says "Click Choose Files to select the CSV file you want to import. After selecting a CSV file to upload, click Open." whenever I choose my file and click Open, nothing happens. I get no error message, and there is no delay. I am returned to the Sessions screen and there are no sessions added. I tried uploading a CSV file of Speakers and that also reacted the same way. No error message after pressing OK to upload the file - just returned to the Speakers page but no speakers are added.

Thinking I might have a formatting error in my CSV file I tried 2 things:

1) I tried to Export my existing data, then erase every line except for 1. In the 1 Session that was left, I altered just the name of the Speaker and tried uploading the resulting CSV file. I got the same behavior as above. [Repeated this with a CSV file for Speaker and got the same behavior too.]

2) I tried uploading the Sessions SampleCSV.csv file to the Sessions area and I had exactly the same behavior. [Repeated this with the Speaker SampleCSV.csv file and got the same behavior.]

So, it seems like either this functionality simply is not implemented, or there is some problem with the SampleCSV.csv files themselves.

Does anyone have any further information on this? Advice? A sample file that actually works?

At this point I will enter all my entries by hand, but I do wonder what might be the problem for me. I expect to have more sessions and speakers to add in the next few days so I would LOVE to be able to do it through csv upload. Thanks.

 I had tried thousand times, either one person will be erased when two people are in the same camera using virtual background. Is the camera only can capture one object in the virtual background? Is any setting or equipment required for multiple people in the same camera when using virtual background?
