You're the only person who's agreed with me on that matter!

Thanks for making me confident that I wasn't imagining the situation.

Might I suggest, the increased condensation after CWI could be from
moisture wicking through the wall into your house as the insulation
dries. after a period of time, I would expect the increased condensation
problem to go.

A bit like when you have your walls plastered.

Though I'm not an expert on the subject.
