Hi @fpwong,
One of our devs ran into this issue where in ControlRig and AnimBlueprint editors, the D keyboard shortcut that is used as “disconnect pin link” is still active when that editor’s preview viewport is focused.
So if you have a pin highlighted and you go and WASD in the adjacent viewport, its going to disconnect that pin and you aren’t necessarily going to notice. The D input in the viewport is also just blocked unless you hold it for a few seconds.
For now we’ve disabled BPA in the ControlRig/AnimBlueprint types in the settings, but focusing the viewport in those editors should just remove any pin highlights. That is what happens in the Blueprint editor. I tested by re-docking the Blueprint Editor’s Viewport tab so that I would have a split view like in ControlRig/AnimBlueprint, and the highlight on the Frequency property in the example below will correctly disappear when I focus the viewport.
