Unreal. It keeps crashing on my updated Note 9 phone. Cannot even open it. It used to work just fine. Fail. Uodate: Google recommends clearing cache, re-installing, etc to everyone (almost bot-like behaviour). I did all that. It still does not work. Google: Duo has a serious bug. Please fix it or lose users in droves. Dear Google AI Bot: Please have your developers fix your Duo app code. A recent update seriously broke the application, and standard user-actioned fixes are not useful.
