I’m sure I’m not the first person to point this out. But definitely not the last.
How does this design make any sense?
You can’t use the mouse while it’s plugged in.
And, possibly even more frustrating, there is no LED indicator so you know if your mouse is charged. Non-technical people like me might spend 10 minutes troubleshooting bluetooth connectivity before realizing that the device isn’t even charged.
Do better Apple!
