I use the Windows client and the Android client, sync’d to Onedrive.
I had a given note open for viewing in the Android app. I then updated the same note in Windows and waited 10+ minutes for it to be synced. I then clicked the Edit button on the note in Android and, despite having the updated version of the note available on the device, I was presented with the previous version of the note to edit. Seems like it should have retrieved the most current version of the note, that was already on the device, before going into edit mode.
