I just started a new Reading Plan in NASB 1995. On my desktop all notes and highlight show. Even from all previous Bibles used.
But none show up on my Android Samsung 8.
On desktop, there is a feature which allows you to view notes made in other bibles. This is not a feature of the mobile app.
It worked when I read in my ESV?
Not on mobile. If you saw the note in the ESV it was because you took the note on mobile.
