Needs to work when there’s no Internet
Received a response from developer that app needs to be logged in every so often, or you have to log in again, maybe you could add a property that makes the app offline all the time, this might help people who only have Wi-Fi access occasionally, and no cell service, thinking of homeless, etc, extended backpacking trips, etc
Response from developer
Hi sale-em-up-scotty, we're sorry for any inconvenience. After an extended period of inactivity on an account, users will be required to sign in again with their username/password and complete the two-factor authentication step. Without service, you won't be able to get the verification code. That said, we recommend signing into the app prior to travel to ensure they can access key credentials.
