I asked the question Confusion over QM Free Particle Propagator - Shankar 5.1 last night and it was closed as a duplicate earlier today, because it is similar to the question Free particle Schrodinger equation: propagator.
However, the (apparently automatically generated) closure note states the following:
If this question doesn’t resolve your question, ask a new one.
As far as I can see, this is precisely what I did. The previous question and its answer were not sufficient to resolve the question for me, so I asked a new one. I tried to make it clear in my new question why the previous one and its answer didn't help and what aspects of an answer I thought would help to resolve my issue.
So, I have to say, I am confused as to what the site policy is regarding asking similar questions to previous ones and what I should do in this situation, where an answer to an existing question does not help. From my point of view, I did precisely what the closure note says and my question was closed anyway. If that advice is no longer consistent with site policy, perhaps the note should be updated to clarify? Tbh, that note seems to be rather contradictory, since it seems to be recommending to someone to do what got their question closed in the first place.
I'm sorry, but for me the existing answer to that question simply does not provide a good enough explanation.
