I cannot see any issues. Are you referring to a markdown or plain text file? Do you enter a regular line break (Shift+Enter) or a new paragraph (Enter)?

[cwmke]

Using a markdown file. I didn't realize there were different line breaks but I just tested out Shift+Enter with the same result. Console shows the below errors.

Line-breaks of empty lines are still removed on Nextcloud 21 RC1. Any reason why these are removed? Is this done by intention?
