Hi Philip,
Thank you for your answer!
I'm the Tudmotu from SO :)
We don't necessarily need a "support person", but we think maybe the StackOverflow comment section is not the easiest way of communication.
We have a lot of questions and we'll probably have a lot of back-and-forth. In addition, we are also interested in sharing from our knowledge and data to help improve Core Web Vitals - but we cannot do that in public channels unfortunately.
For now, we will keep using the suggested channels (here; StackOverflow) but if there is a more direct means of communication (even a Slack, like AMP's Slack for example), that would be greatly appreciated :)
And again, thank you for taking the time to answer the SO question.
