I2C/Qwiic issues with 2.1.1 and ATP board #432

Ardunio 1.8.16 on MacOS

I have been out of the loop for a few versions, but after upgrading to 2.1.1 even example sketches fail to communicate over I2C. I can use modules like the Qwiic SerLCD and Qwiic OLED, but Qwiic buttons and LED sticks don't respond.

Running the I2C scanner sketch with one qwiic button attached:

Looks the same issue as https://github.com/sparkfun/Arduino_Apollo3/issues/400

Apologies! I did search and must not have had the right key word combo! That does look exactly like what I'm hitting as well.
