For about two weeks now, I notice that emails “randomly” end up in trash.
It usually are messages that I read and then marked unread to revisit them later.
Next time I open K9 they are gone. And when I search for them they aren’t found using k9, but on my desktop I can find them in trash
I can’t reproduce the behavior reliably, but it’s happened with more than two dozen emails in the last two weeks, so I highly doubt that this is user error…
