Forking this off into a new topic since it's not related to my original question.
In the email quoted below from Rich, I see that he is quoting someone by the name of "Reid". I don't see any emails from this user but a quick search of my inbox suggests that he *might* be using a protonmail account. I assume this means he replied to my question but I seem to be getting everyone but him. Can anyone confirm if this is the case? I've encounted some strange problems since moving to this service for PLUG and this adds another datapoint.
