"tone" for buzzer ? No acceptable?

Butit still won’t upload because it refuses to see the library.

Gotta say, PIO library function sucks too often.

I’ve spent at least half the time I’ve spent with PIO losing my mind over these stupid libraries.
And this one was installed by the PIO library tool. And it’s in the project’s /lib folder.

Fails too often. It’s insanely frustrating. And these are Adafruit libraries. No reason they wouldn’t be just known.
