I appreciate the response, and I have gone through that post, but if there is a solution there, I cannot identify it, much less understand or apply it.

That is why I am asking for a solution that is described in a non technical way.

Further to this, it looks like this is a longstanding issue. Why is it that the devs can’t dedicate a bit of time to come up with a solution that can be used by anyone? It is really astonishing that it is so difficult to get one’s account history. Every other platform makes this simple.

It's due to the decentralized nature of the blockchain. We are forced to copy the chain into a database in order to get decent performance for history queries and of course, the database itself is not decentralized, so it's not a logical fit. This will happen in time.
