Hi - this seems to be a bug, but every now and then, randomly, the Escape and Delete keys stop working in Layout. This is on a MacBook Pro, IOS Version 13.4 (22F66). The fix that I’ve found is to close out of everything, shut down and restart Layout. Layout version 23.0.418 (and before).
Not a big deal, but it happens once every few days. Thought someone should know!
