Does the Zoom PRO license have the interpretation function available by default or does the account owner with the PRO license still have to purchase a Zoom Webinar license to access the interpretation function?

For context I will add that I use the Zoom interpretation function on our Business License, so I don't know what the current status of the Zoom PRO license is.

I'm using a 2020 MacBook Air with Zoom. I have wired earbuds from Apple, and also 3rd party ones, that work fine with the computer when I'm on any other website with sound (Netflix, YouTube, Hulu, etc.) The audio works fine on Zoom when I join a meeting and join by computer audio, but when I plug in the earbuds to the computer port, there is no sound. I've tried 3 different pair of earbuds and I've googled this question for answers. I see other people have the same question but I have not found a resolution. One answer was to change the settings or preferences on Zoom but I don't see where to do that. 

Thanks.

Currently, Zoom saves local recordings with folder names that tell us what the meeting name was and what date and time the recording was done. But these settings are not translated into file names. The file names seem more random. We have to move the recording around, e.g., upload it to Vimeo to be shared in other places, so we have to manually name the files by copying and pasting the folder name into the filename. This wastes time and creates the possibility of user error. Is there a way to get to set proper filenames using the meeting names and times? Shouldn't Zoom be doing this by default? 

Short explanation of problem: I have an active meeting running. I leave it and make my coworker the host. Then I start another meeting. This kills the first meeting.

Question: How do I configure both meetings so that starting the second meeting doesn't kill the first one.

Long description:

My company and I own two zoom accounts, both paid, both registered under the company. I've listed my coworker (owner of the second account) as a cohost on the first meeting. When I need to leave the first meeting, I make my coworker the host, I leave (I do NOT end the meeting). Then, I start my other meeting. Starting the second meeting ends the first meeting.

1. Why is this occurring? I pay for two accounts for THIS very reason - so each of us can operate meetings separately and independently.

2. How do I configure zoom so this doesn't happen?

Thanks!

We have a virtual meeting with multiple attendees. When someone speaks there is a reverb/echo for everyone. What settings do I adjust to alleviate this issue when using a bluetooth hearingaids. As the moderator and have dialed in on a personal phone to hear better rather than using the computer audio/speakers.

Thanks
