The old days of calling recon and coming away with a good result have changed (Chase Recon: How to Get It Done, written in 2016). I applied for the Chase Sapphire Business card. Instead of getting the 5/24 rejection, I received the following reasons for rejection:

Baffled by the seemingly contradictory reasons, I called recon. I was told the decision was final and nothing could be done. Curiously, I have never been approved for the Chase Sapphire Reserve personal either.
How I would have met the minimum spend is no longer an issue (see Oops!… I Did It Again: Min Spending Hell).

Assuming that the reasons are accurate, having high balances on non-Chase cards while not using your Chase cards much might have been the deal breaker, implying that you use your cards a lot but not their cards. I’m also not sure what the second reason even means.
