My concern is that some time ago, everyone could just access and modify their notes offline without problems.
Now, Premium says:
UNTETHER YOURSELF
Capture and access everything that matters on all of your devices, even when you’re offline.
I have already had problems when I have no connection (notes won't open) and now this... It's just frustrating to write a long paragraph and, after 5 minutes writing, its gone, no conflictive notes, no automatic backup note... just write it again and try.
I may try that legacy client though.
