Using Meeting SDK Without Publishing

I do not plan to publish my app on any app store (Google Play or App Store). I only want to use the Meeting SDK for internal or private use.

Is it possible to use the Zoom Meeting SDK without publishing the app?

Will I need to go through any approval process for SDK usage if my app is private?

Domain Verification for Multiple SDK Accounts
If I use multiple SDK accounts, but all meetings are hosted on only one domain, do I only need to verify that single domain once? Or does each SDK account require separate domain verification?

Development vs. Production Keys
I noticed that there are two types of SDK keys: Development (dev) and Production (prod).

Which key should I use for my application?
Are there any restrictions when using dev keys compared to prod keys?

Do I need to switch to prod keys before deploying my app, even if it’s for internal use only?

I would appreciate your clarification on these points.

Looking forward to your response, also I would appreciate any advice if there is a better way.

In my online Zoom account, under settings, I have "Waiting Room" turned off. However, when I set up a meeting (it doesn't matter if it is a scheduled meeting or a "start meeting" where I then send an invite link to people) people are put in a waiting room. We're just trying out zoom for a new business, so apparently, I don't have access to either phone or chat support, so I'm hoping this community can help.

Thoughts on how to fix this? Success is simply that when people join a meeting, they get right in without having to wait in a room and be admitted, regardless of if it is a scheduled meeting or a start now-type meeting.

Thanks for any help.

Hey there - seeking reassurance. I am leading a workshop in a while. In the past, when I've hosted, I've been able to open and close meetings, setting up whatever, via a "Join meeting" or "Launch meeting" button thing. Now, though, despiute seeing this in my schedule, along with confirmation that i'm the host, no "Join" or "Launch" option is available, and instead I need to to access the room by putting in the Meeting ID. Should I be worried? Or has the way we access rooms changed during some update?

I see this pretty consistently in the Web UI:

- In a meeting, have people chat (enough for the chat pane to scroll)

- Make sure there are replies to chat messages in threads

- Scroll to the bottom of the chat pane (or be anywhere really, including scroll up and down while the next step happens)

- Have someone else add a chat message anywhere

- Observer that chat pane jumps up automatically every time there is a new message

It looks like Zoom is _trying_ to keep the chat pane focused on the same place when it refreshes with new messages, but miscalculates the scroll position. Given that the jump is always upwards, it's almost as if it doesn't take the reply-in-threads into account when calculating scroll position.

I set up zoom meetings with the goal or hope that zoom would automatically send an invitation to the client. It has not been doing that.

Due to this, I integrated my microsoft 365 account to zoom and checked off all boxes at the bottom of the profile tab in zoom. It still doesn't work. Instead of it clearly going through to the client, I get an email kick back and error instead saying 

Delivery has failed to these recipients or groups:

I tried contacting microsoft for help but this seems to be happening from zoom to 365 sending out invites. Has anyone else have the problem or know how to overcome this.
