Useless app and chatbot support for claim rejection enquiry

Discovery health app is terrible to use and keeps disconnecting and crashing when trying to use it for support assistance. There is also no way to get reconnected to the agent that helped you before it disconnected you. If i could give zero stars i would definitely do that. Needed to get 2 different injections and discovery refused to pay for both needles after payment was submitted from the medical provider. Absurd! Trying to get to the bottom of this but cannot seem to use the app or chat bot as it keeps crashing.
