Hi,
Thank you for creating and maintaining K-9 Mail. I like it much better than the default mail app on my Samsung Galaxy S8. I have one problem many times when writing a new message. When it saves the draft, if I reopen it, the message is blank. It happened just today with a long message that I worked on intermittently over several hours. It saved at least 10 times, but when I reopened it, it was blank. I backed out of that screen to the Drafts folder, and the latest version there had only the first few words. I thought I saw a bug fix related to this years ago, but it still happens to me. I’m using version 5.600. Thank you.
