This is an odd one - I’m struggling with DT suddenly losing focus. I’ll be typing in a note, and then use the keyboard arrow keys to navigate, but instead of navigating the text window, the arrow keys are scrolling through suggested spelling options in the touchbar. This has just started, so I’m not entirely clear what conditions are triggering it.
I updated to 10.15.4, so that may be connected. DT 3.04.
