I've installed macOS sierra (beta) on my MBP & iOS 10 (beta) on my iPhone 5S. Both of them have the latest release. I've connected them in the same wifi network and Bluetooth connection is also active on both of them. So the two-way copy-paste should work seamlessly on these devices. The problem is, copying on MBP & pasting on iPhone works fine but the reverse doesn't. What to do to make this working??
