Apple notes not syncing with Gmail notes

I use Apple Notes in iOS 10 and it is synced with Gmail Notes. I use Gnotes on my Android also synced with Gmail notes. Gmail notes does not sync with Apple notes properly.

Issue:

When I make a new note in Apple Notes it does show up in Gnotes but not the other way around. I edited a note in Gnotes using my Android phone. It shows up in Gmail notes but then it doesn't show in Apple notes. I've got 66 notes in Gnotes/Gmail Notes but Apple notes only syncs 39.

Attempted solution:

Went into Gnotes, signed out of Gmail which deleted the, on my Android. Then went into iPad setting and turned Gmail notes off which deleted them on the iPad. Then turned both back on. Gnotes imported 66 notes from Gmail notes but only the 39 notes came back and not those made or edited using my Android.

Anyone know how to fix this?
