Hopefully, this is a new problem and not something that has been going on and I wasn’t aware of it.
When tracking is turned on with “deletions in the margin” checked, it looks great until I close the document and reopen it. When I reopen the document, I’ve had as much as three lines of text deleted when I only deleted one character.
Here’s an example.
I’m using Windows 10, V21H2, 19043
LibreOffice 7.2.4.1 (x64)
Java 1.8.0_291
