Ipad pro can't "see" the magic mouse 2

I used to work with Magic Mouse 2 on my Ipad Pro v13, but since the last update 13.3, now the mouse is not even detectable via Bluetooth … Try everything from resetting the network to restarting, turning on / off, mouse , accessibility, not even detectable on switches and so … The mouse works fine on other devices, but the iPad Pro … Any ideas?
