HI there!
I know there was at least one similar post to this one which doesn't seem to have been resolved, but I'm hoping maybe someone has figured it out since then.
My pose morph tag suddenly stopped working when I went back to make changes after animating. It instantly undoes any changes I make to a pose now, even new ones. The old poses all work fine. It seems to go hand in hand with another glitch, which is that my move and rotate controls keep flickering out of existence. I'm attaching a video for more detail. Thanks for any help!
Notes: I do have "edit" mode toggled, and it's only a PSR pose morph (not points), except that it's on a rig/hierarchy. which might be complicating things. There is a bit of xpresso linking the pose strengths to a Maxon Moves object, but that didn't affect my ability to make new poses or change old ones before this.
