My org is switching from Classic to Lightning, and I have noticed that the feed actions do not load the first action, but if you select any other action they will load and then going back to the first will load it. Refreshing the page starts everything over again. I have tested this with a standard Update Record action, lightning component, and a flow action. All 3 do the same thing when the record is loaded, it will say "Create New..." and when you click that it will load the action.
Does anyone know why this is happening, as it is only in the Lightning Experience not in Classic.
