Mask Path Keyframes Not Animating in Premiere Pro Beta (v25.6.0)

Have the same issue in 26.0.1. Trying to animate a mask, but Path keyframes are not working. When I modify the mask, it doesn’t even update the keyframe.

This is such a core function of the software. How is this not working?

I was able to get one keyframe to follow path, but only one. Tried again and it would not work. I too tried all different ways. I did find this article: 

Solved: Mask Path not working properly

The issue with the mask path not following the path in the updated Premiere Pro can be attributed to a bug in the current Premiere Pro Beta (version 25.6.0). Users have reported that when drawing a mask using the Pen tool or shape tools and attempting to animate it with Mask Path keyframes, the mask does not respond to changes, and both keyframes remain identical, staying static. This behavior has been confirmed in multiple projects, and none of the workarounds provided have resolved the issue. The bug is blocking workflows, especially for subtle object masking in low-resolution footage. Adobe is requested to update the software to fix this problem.  

I cannot believe they would let this pass. Those in charge should be FIRED! This is lost time and money in our field. I know others in the field and they all say Adobe is losing the battle with other video app makers. May be time for us to move to another video creator and end Adobe.

The clip and frame mode options are so unnecessarily confusing

Having the same issues in v 26.0.0.  Keyframing the path of a pen mask won't actually save the moved path.  I’ve had to open Pr 2025 to do what I need on the one video and then import that edited video back into 2026 to keep working on the project.

EDIT: Frame mode suggestion from Ann (below) solved it!

But...why? Don't let me put keyframes if they wont work. This is not a good design, they should block keyframe addition and show some message like "change to frame mode to use keyframes".   

For animating masks manually you need to be in FRAME mode (program monitor)

Use object masking in Premiere Pro

Same issue here. Unable to manually adjust regular pen mask path keyframing, which is super unfortunate. Hope they update it really soon.
