Unfortunately, the iPhone 6 I had was so old it could not be upgraded to IOS 13 at all. I think that may be the issue. Regardless, I threw in the towel and just bought an iPhone SE. They may fix the issue for older phones by the time we are at HS next week, or may not, but I did not want to risk it. I feel a little silly, but the SE is a good price, and my phone could use an upgrade anyway for battery performance and memory issues. Issue went away completely on the newer phone so I do think it was my old phone that was to blame.
