Galaxy Tab 12.2 SM-P900 can't connect to bluetooth mouse after Lollipop

[AC Question]

As the title states, I'm unable to use my bluetooth mouse. It pairs with the mouse, and even checks off the box 'Connected to input device', but I do not see the mouse cursor.

Prior to upgrading to Lollipop about an hour ago, the bluetooth mouse worked perfectly with the tablet.

Is it possible to revert back to KitKatt? Or is there a fix for this issue?

You can revert back to KitKat by rooting your device.
