I've also had notes that I created which indicated "All changes saved" in the lower right hand corner, completely disappear after I closed the note and tried to access it minutes later. This occurred on 1/3/23.
@agsteeleEvery time I go to Evernote's support page, it tells me I'm logged out and when I log in, it still indicates I'm logged out. In this state, I cannot submit any tickets - only browse the forum.
