If you are having issues using the iOS or Android app, the following steps clear up most issues:
Log out of the app, restart your device, and log back into the app.
If that doesn't resolve the issue:
Exit the app, turn your device’s Wi-Fi off then on, and open the app again.
Check if there is an update for the app (via the iTunes App Store or Google Play Store).
If updating your app doesn't resolve the issue:
Try uninstalling the app and downloading it again.
Also, make sure your device's OS version is compatible with our app:
For iOS, the OS version must be 10.0 or higher.
For Android, it must be 5.0 or higher.
