Well, if you are not a perfect human being yet, you are going to have certain views and opinions that will change with time based on new information, and that is fine. You may answer a question one way today, tomorrow you learn new stuff and answer the question a different way. I am not quite so sure about finding both answers helpful and beneficial if they are conflicting. So I would have to be given a specific example to know if both answers were helpful and beneficial, because why would you want to change an answer if they are conflicting with each other?
If I change a view or opinion, generally I change it because I want to make it a better view and opinion. Maybe that is the key, the first one was not so bad, it was a starting point but then I learnt new information, I built on that, and I adjusted my first view so the second one is now better. In that case both answers may have been helpful and beneficial at that particular time, but now I have a better one. So I think that is maybe the answer here, "What do you recommend in trying to reconcile these differences?" is to get to a better answer. The new answer that you have on the second day, is it actually better than the first one? Because, If it is not, then you are not going to want to take it.
If you are confident that the new understanding is the way to go, then you can easily let go of the first one.
Now let us say you are not too sure the second one is better than the first one. Then you need a good friend. That is when Kalyanamittas, good, kind, wise spiritual friends are important. Go to a good friend, discuss it with them, see if they can give you good information. You don't want to have two views of the same thing that are conflicting with each other, because then you are sitting in doubt, you don't know where to go. You need to pick the better decision or view and then stick with that, otherwise you get stuck with doubt.
