Yes I actually faced this exact bug myself a week ago. What happened was - my mobile app gmail displayed my draft as sent (but actually I have already completed it and send it using desktop web app), but when double checked on desktop, it indeed actually send my completed email, not the draft.

I tried restarting the app/ refresh email threads, but it didn't fix the visual bug. I'm not sure if the bug is still present today as the email thread has been buried down and I couldn't care enough to follow up on it. I'm just glad it didn't actually send my draft when somehow the app displayed my draft version as sent.

Note that I'm not a user of K9, I'm just describing similar buggy encounter with Gmail desktop and its android app. I only noticed this that one time and just shrug it off due to me turning off apps auto update. Usually I only update manually when I really think I need to and after carefully reading each change logs.
