I didn’t realise who you were. Well done and thank you.
The plugin now seems to cause the max attribute to be set to 0, and this disables the numeric functions in the mini cart. You can test this here (after adding something to the cart first).
The cart shortcode is still OK, but the cart block causes a server error with this stack trace:
