Absolutely do NOT use the app to attempt to use your rewards points if you are a Chase credit card customer. USE THE WEB version. Worst experience ever and I finally just gave up (I'm sure that's what they wanted). Hitting the back button on your phone just one single time takes you ALL THE EAY BACK to the main accounts page. After trying again several hours later, the rates for the save hotel room I was attempting to book went up by $50 per night! Also, no dark mode. Seriously chase?
