It requires you sign in to a Microsoft Account for it to TRY TO work
ftfy, i wanted to give it a shot one time and it literally didnt work, at all. all of Microsofts cross device features are a hot mess, like how you are supposed to be able to share the clipboard between logged in windows PCs, never could get that working either.
but you shouldnt because snap's "strict confinement' sandbox feature does not work without the legacy patches to Apparmor that ubuntu uses.
