Just wanted to chime in and say I'm having the exact same problem with a MacBook M1, Seqouia 15.5, 64GB ram. I haven't tried Beta 3 so I can't confirm whether that'll fix it. -- Update: That was an an old Vision OS project (Vision 26). If I create a brand new iOS 26 project, playgrounds seem to work properly.

If anyone has any greater clarity on this I'd be -beyond- thrilled to hear about it. I've tried the workflow defined above, to little to no success. I've worked through the "Compose Interactive 3d Content..." project, and the thing that's very much unclear to me is how those USDZ assets get set up in the first place. More specifically: Their Animation libraries look like this, and mine never do out of Blender, regardless of how I export them. I'm currently trying to get facial animations on a character out of Blender and into RK. Any help would change my life thanks> Phil

Sigh, of course I misspelled inaccurate in the subject. It's been a long day.

Yes, I have this problem. I think it's due to shoddy wifi, at least I get it more or less frequently depending on which of my wifi router/extensions I'm connected to.

It appears that VisionOS has changed this so that it -does- support Blend Shapes as of OS 2.0 (https://developer.apple.com/documentation/realitykit/validating-usd-files#Review-skeletons). Does anyone have -any- idea how on earth to get them to work? RealityConverter doesn't seem to see them.

** POSSIBLE SOLUTION ** I had this same problem on every Desktop Browser, but then was able to log in and accept the agreement using my mobile (iOS Safari) browser just fine.
