Fix email threads!
This has been broken for at least 5 years (maybe 7 years) and I've reported it a few times. Support ultimately decides they don't care this is broken and closes the ticket.
If I spend too long (varies between maybe 10 and 60 minutes) writing a response to a thread, the browser's editor will reload (I guess -- the editor page jumps). Aside from interrupting the typing, the thread conversation history gets chopped down to 2 messages (current and 1 previous).
If you browse for the older messages, you won't find them. If you use the search bar to search for the older messages, you won't find them that way either! But... they aren't deleted either!!! If you turn off the "Group by conversation" feature, they are still there. Turn it back on and they are magically gone!
Occasionally -- once in a blue moon -- the threads will fix themselves months later. But... usually not.
This is with Mail Pro and regardless of browser: Firefox, Chrome, old Edge, new Edge.
