(SOLVED) _BV macro unknown at Nano 33 IOT and Nano 33 BLE

I found the next annoying incompatibility with the new NANO types: The _BV macro is only accepted by Nano Every. Neither Nano 33 BLE nor Nano 33 IOT know it.

This macro is often used in the library "Bounce2". This library should be used by any beginner, that would prevent dozens of questions in the forum!

Found and installed a newer version 2.52.0 of the library Bounce2. It is no more using this macro and works with all new Nano variants.

Thanks for the update.
