Orachi v2 Bluetooth not connecting after mouse goes to sleep

So I have owned 3 copies of this mouse now and get the same issue with each one - I've done some searching and seen its not just me. I get this issue with all the computers I have tested it with, 3. the steps to recreate are: 1 - pair mouse with pc 2 - leave mouse to go to sleep OR switch to 2.4/off 3 - wake mouse up OR turn it back to bluetooth mode 4 - try and use mouse Out come - mouse does not reconnect to PC To reconnect it I have to turn the mouse back to pairing mode and re-pair it again so that I can use it. I have also have a few other bluetooth mice which don't have this issue and work perfectly with all pcs. It's a great mouse, but it's a real shame you can't implement bluetooth in a useable way.
