The bootloader version my M4 came with was 2.0.0. It appears to update to the most recent version--as per steps enumerated in the ItsyBitsy overview--however, when I remove and reinsert the board from USB, it has reverted back to 2.0.0.
I've repeated the process several times with the same result each time.

Interesting. That (the v3.15.0 version) is not what I was using. Not quite sure how I messed that up.
Anyways, thank you for your prompt response!
