I have Drafts 16.1.3 that I use on iMac. Yesterday when I used Draft maybe two days ago on this machine, the notes list view was all blank, except for the borders. The uppermost note was much bigger than usual. I tried all kinds of tricks to show the notes, such as resize the window, hide and show views, etc, but nothing helped. I could “reveal” a draft by sliding left or right with the trackpack left or right, which shows Trash, Archive, etc actions.
Then I got it working, possibly by quitting and restarting Drafts. Now it happened again. It’s possible it’s caused by some interaction with the quick note action which I’ve also been using. In any case, I’ve been beta testing Drafts for a long time, and this thing hasn’t occurred to me before. Unfortunately I didn’t take a screenshot of it, but I’ll take one if it happens again.
