It has been a little over a month the app for iPhone doesn’t work. All it does is stays blank, white screen for about 30 sec and disappears whenever I click on the app to open. I have re installed the app several times, i am updating the apps thru the App Store daily, I have reset/turned off my phone, I called the customer service help desk number and no help. Please fix, I am running iOS 14.5
