I'm using Team Projects for After Effects and have a face-composition with a nested mouth-composition two levels down in the face-composition.

From the mouth-comp I've added some Essential Properties to the face-comp. This works.

When re-opening the Team Project however, I get the following error:
"After Effects warning: Could not create Essential Graphic parameter because it refers to a non-existent layer."
The file opens but the master properties referring to the mouth-comp on the face-comp have all disappeared. Needless to say that is a serious problem because all keyframes added to these properties are lost.

Don't know if this is a bug or a limitation of the Essential Graphics or Team Project workflow. But I believe it is worth taking a closer look at.

Thank you.

Note: I've been able to repeat the bug so it wasn't a one time error.
After Effects version 17.6.0 (Build 46).

Especially when dealing with multiple layers and parameters within each layer, it is frustrating to have to manually navigate to open and view each keyframe. Wouldn't it be nice to have a shortcut key command that automatically expands parameters within each layer that have used keyframes? That way I can quickly go to the parameters I need adjusting quickly. I understand there are shortcuts that lead to individual parameters (ie, "T" or opacity), but usually one would animate multiple parameters alongside each other. To have one shortcut that opens only the parameters that contain keyframes as a starting point for navigation would increase efficiency tremendously.

My Prores 4444 Footage w Alpha that is premultiplied on Black, only acts normal when I am in Half resolution preview. As soon as I switch to Full Res or Render, the Alpha is treated as Straight/Unmatted.

Interestingly… if I select the interpret footage option "invert Alpha", the Alpha is only inverted when previewed at Full Resolution, not at reduced resolutions.

When I employ the workaround of adding the effect "Remove Color Matting" (Black) myself manualy, I also get very weird halos and artefacts when previawing at half resolution, which are not a side-effect of simply downscaling.

This occurs in CC2020 and CC2021 (not in Beta 18.2)

Why did you get rid of it in the first place??? We were used to it. It worked!

You added all these nifty camera tools, like orbit around cursor or scene. Which would be fine. Except I want to change something and now it doesn't work the way I'm used to. Like using my center mouse button, which was super useful.

So I have to spend time looking at your documentation. Which is TERRRIBLE by the way. It's super confusing and I don't understand which is the most like the old behavior.

Stop breaking things we're used to even if there's a "better" way. Maybe there's a "better" keyboard than the QWERTY one we're all used to, but there's a reason we haven't changed it in nearly 150 years.

Turning on the 3D Reference Axis in 2020 causes an automatic crash.

For days I've been trying to figure out why some of my older projects were crashing in 2020 when I opened a comp, and I just realized it's because the 3D Reference Axis was on in those comps.

To recreate the problem, simply add a Camera layer to any comp, and turn on the 3D Reference Axis.

I'm on an iMac running Big Sur, but I get the same results on Catalina, and on a PC running Windows 10.

Please fix ASAP. I have products that clients can't open. It's especially urgent because people on Big Sur like myself can not open the projects in CC 2019, since AE CC 2019 is not compatible with Big Sur (Another MAJOR issue!)
