I will be sure to report back. Here’s one thing I already see is weird:

I initially had 18,000(and a little more) miles set to expire on 31 Aug 2019. The day before, I transferred a few thousand miles from Chase so I could book a ticket for award travel in March. That left me with 851 miles, which I assumed they would have expired yesterday. But now it’s 1 Sep and not only do I still have those 851 miles, but it says they now expire 30 Aug 2021. I thought Chase transfers didn’t extend the validity! Do you think it’s just a bug or maybe because I do have a revenue ticket booked?”
