Apple keyboard losing connection
I have 2 Apple keyboards, old model. One at home, and one in office. They intermittently get disconnected. Become completely impossible to reactivate. I have to go to bluetooth Manu and remove the keyboard, and then pair it again. Very annoying. Is this a flaw in BigSur? Anyone knows what to do? I have Apple Mouse setup similarly, one at each place. Works perfectly, so only affects keyboard.
