Nice to hear so many stories of excellent customer support from framework. I echo @Stefan_Holmes saying “This is exactly the way to make me a customer for life”!
On the displayport expansion module, I wonder if there’s some reliability issue with those - they have been flaky for me as well (occassional failure to connect after restart), and I simply switched to another one from CableMatters which has been a lot more reliable.
