Hi there,
Recently bought a Note Air 3 originally for replacing my Tab Mini C but later decided that it's best to set up both devices for different environment and use cases. I'm aware that pdf annotation can sync between Boox devices using Boox account Sync, but can we do that without using the Boox account? Personally I'd prefer if I can avoid not using an account in the first place.
So the short answer is yes you can simply sync the files and annotation through webdav drive and it works decently good.
