Anyone else intermittently losing the Immersive Space (3D) option off of the View menu?

Anyone else having this issue?

I've been doing a lot in Teams Immersive Spaces. It has worked in New Teams for most of the year.

I've demonstrated it in front of live audiences successfully for most of the year too. Until about two weeks ago. I was in front of an audience, went to show them how it works on a Business Standard tenant I've had for about 10 months, and boom, no Immersive Space (3D) on the View menu. I have all the right settings, the right licenses, and it has been working fine until now.

It doesn't matter if I am doing a "meet now" or a scheduled meeting. Alone, or with others invited. I've made sure my version is up to date. I've removed and reinstalled Teams, I've tried it with other accounts, I've done a reset and a repair. I've rebooted the computer. I've tried it on other Windows 11 machines with Teams. I have an enterprise tenant, also was able to use Immersive Spaces in Teams, that also has this issue using the clients on my computers.

It is intermittent. Some of my friends who tried it for me, can see it on the menu (including on the Mac), some can't. It often works once, then the Immersive Space (3D) menu item then disappears, and even a quit and restart of Teams won't bring it back. It does seem to be more dependable on the Mesh admin trial licenses than the paid for Teams Premium licenses for some reason. Not sure if that's a red herring, but I thought I'd mention it.

Also, occasionally, the users I invite (if I do a scheduled meeting and not a meet now), will show up briefly as unknown, when they've had the right licensing for a while, but this disappearing menu item thing happens even with no one else invited.

Anyone else having this issue with Teams? Have you found a fix? I've just really gotten people comfortable using the feature, and now it's not dependable.
