MS Teams does not work properly on Firefox for example (I’m forced to use it once in a while for work). Same with other web-apps that often don’t function correctly.
On Android Chrome manages to stay open while multitasking while Firefox will close the tab 90% of the time requiring reloading the page. That’s especially annoying during check-out or logins when I need to switch to a 2FA app.
the obsidian-git plugin. Auto commits and pulls/push every x minutes. Works great for me, I get full version control and works on all my platforms (Linux, Windows, Android). You just need to be careful with your .gitignore and add at least .obsidian/workspace.json to prevent conflicts.
Probably not suitable if you store larger files, but after a year of daily usage with tons of small images I’m still below 150 MB.
