I am experimenting with WebUSB for my company, as it does have a lot of potential as we move away from native windows applications to more internet browser based applications.
I have purchased a Adafruit Circuit Playground Express and have been following the guide, Overview | Using WebUSB with Arduino and TinyUSB | Adafruit Learning System. My issue is that although I've installed the additional libraries and boards through the respective managers, when I select Adafruit Playground as the board, I do not see the option to change the USB stack!
I am currently using the Arduino IDE version 1.8.15 (I have also tried the nightly build without no success). I can install sketches onto the Circuit Playground Express, such as the demo and that works fine.
Not sure what I am doing wrong, so any help would be gratefully received.
Arduino IDE v1.8.15
TinyUSB Library v1.4.2
Arduino SAMD Boards v1.8.11 (This includes the Adafruit CPE board as I presume the Adafruit SAMD Boards have been replaced by this one.)
