Question about Onyx Boox Note Air 3

Yes, it works seamlessly between my One Note on Samsung phone and my Note Air 3. Any modification made on one device is automatically shown on the other.

Yes, it works. Please note that logging in with a secure MS company account for Office 365 etc. does not work because the Microsoft company portal cannot be installed on the Boox.

I do not use OneNote.
Best regards

Hello, it works. As the Play Store is available, OneNote can be installed. However, taking handwritten notes is clearly not optimal. I recommend taking notes using Boox's in-house application.
