Yes me too since a couple months :( So annoying. It doesn't of course happen on Windows.

It started with OneNote web a couple years ago. Every day that gave a popup "Your session needs to be refreshed) and it would reload all over again. Microsoft don't bother to make a OneNote desktop app for my platform and the web version is really terrible anyway (you can only search in one tab, not a whole notebook). So I moved to self-hosted Obsidian which I'm really happy with. Now I can basically see myself typing in a note from another client.

But replacing Microsoft for email is another topic.
