This isn't app at all & no different than a mobile website, only WORSE! I intended to use this app is to avoid entering login credentials and use fingerprint instead. And that ONE THING is broken. The app prompts me to log in at random times and biometric login doesn't work at times. I can't believe Costco doesn't recognize the value of good UX for driving up online sales. Update: today I didn't order items in my cart because I got frustrated that a 30 second thing is taking me 10+ minutes!
