Help Bluetooth keyboard doesn't work after system update

[Android Question]

Last night I was prompted to update my Galaxy Note Pro, I assume it was updating to 5.0.2 since that is what it shows in system info. After updating, my Logitech Bluetooth keyboard case doesn't work. It is paired and when I turn it on it says Bluetooth keyboard connected, but does not register any of my keystrokes. It worked fine before the update. Any ideas?

Can you try unpairing /pairing them? (guess you've tried that).
The update might have changed the Note's bt address (or whatever)
Is the keyboard supposed to work with lollipop?

This is a well known "feature" of the latest Samsung update to Android for some devices. It has broken not only Logitech Bluetooth but other makers' kit too.

Samsung at first tried to pass the buck to Logitech but when the two compared notes, Samsung found that it had missed something important in the Andoid update.

Here's the Logitech response:

We would like to inform you that Samsung has identified the cause of the problem on the Tab PRO and the fact that our keyboard stopped working with it on the latest OS update. They have urgently updated the binary file and the OS will be updated soon. They will get back to us the OS release schedule.

As you can imagine, this has caused quite a heated exchange over on the Logitech forums.
