I'm surprised this is still not a feature since this post is from 2020. Would be extremely helpful since I am constantly switching between devices and would like the ability to trigger a sync so the content is up to date when I need it to be. Unfortunately, it still doesn't always sync when I quit the app on both devices I use GoodNotes on. Will try the suggested workaround posted below.
