Add a sync button on the main bar to the different goodnotes platforms. I simultaneously work between goodnotes on my MacBook and iPad. It rarely auto syncs in real-time. I need back out of my current document in both platforms, go into settings, go into icloud settings, and then click use icloud. I toggle off in both then toggle on in both for my changes to sync real-time. It's a nuisance. I love goodnotes otherwise.
