Test before release
Not an angry pointed suggestion but these days so many releases I'm immediately finding bugs meaning I have to revert to an earlier version. To the point where I now always make backup copies of Excel & OneNote before allowing an update as well as checking Time Machine is up-to-date. And I'm reverting to those backups so often it's getting a bit daft and I'm now at the point of looking at LibreOffice. Maybe a few votes to get Microsoft to put a bit more effort into pre-release testing.
I can appreciate there is pressure to get new features out there and get bugs fixed but users are "paying a price"
