Earlier quoted context omitted.
This should be the top answer. The product is simply not ready - as evidenced by a two month delay.
Is the two month delay evidence that the product is not ready now, or is it evidence that it was not ready two months ago? (This is a rhetorical question. You don't have to answer, because the answer is self-evident.)
Two extra months isn't going to fix that IMHO. If you are struggling to get a minimum viable product, it's worrisome.
Who knows though, maybe the problems they had were in the actual manufacturing of them.
