Additional features, settings, or issues not covered by specific Microsoft Teams categories
The best workaround I have found since the additional updates (regressions) is to forward the message in TEAMS, then copy/paste the message somewhere else (Word?), exit the message forwarding to get back to "normal" in TEAMS. You can then edit the message you are "forwarding", but it will keep the date/time stamp and the name of the person who made the post.
Check my work?
The Windows platform has been and always will be a garbage product because of issues like this. It would be nice not having band-aids and "workarounds", or better yet, stop changing things and leave it alone. Quit breaking everything. Please pass this on to the Microsoft overlords.
And the "workaround" does work, but this is getting really old.
