QB Support says this is a global problem - I find that hard to believe that no one is able to use QB mobile apps if using a QB Online account. I have tried multiple devices, multiple iOS versions, multiple versions of QB on my devices and the result is the exact same. When I open the app - I am prompted for my login details, select my company and the app hard crashes back to the iOS home screen. It happens when using username/password or FaceID to authenticate. Been using QB for 7+ years and I have not been able to use the mobile apps for months.
