Update:

The development and QA testing of our new Universal Mac Applciation have concluded and is included in our 23.8 release.

If you are interested in early access it is available as part of our Canary build for 23.8 which was released last week, stable release is tentatively scheduled for release the week of October 23rd.
You can learn more about our release channels here:

We'll be sending out the Beta test link on Monday or Tuesday next week, so be on the lookout in your gmail account for the link. I'll post here when it is live!

This can be accomplished by going to the Administrationupdating the key SessionInfoPanel.MakeSessionPublicVisible to Custom and setting the value to false.

No, see my post above from Tuesday

Sorry to hear you have run into these issues in the past. 
The first issue you mentioned about reboot is being addressed, but because it is a bit of a risky change, we'll be releasing the fix in a release after the new update.

There is an OS level limitation that will reset the Media Projection permission when the device is rebooted, we'll be making a small change that will notify the user to set this permission on device reboot. If a user were to ignore this dialog, we'll not be able to record the screen until the permission is set, in this scenario the prompt will appear on the end user screen when a host attempts to connect. 

Yes, unattended sessions should continue to work as they do now:

Update:

This effort is currently in QA and is tentatively scheduled for our 23.8 release. I would expect the release will be available in late-October.

We have started the app approval with the Play Store. Since this will require using the Accessibility functions of the device, we need to demonstrate that we are giving appropriate prompts to ensure that end users are given the chance to decline the setting. Since we had to submit a video, I figured I could share it here, it was created by my engineering colleague, Mrinal:

We are making good progress here, so be on the lookout for some updates very soon for our beta testers!
