Restart the application

To completely close an app, you usually need to bring up the multitasking menu and either swipe the app or press the cross. The process may vary slightly from phone to phone.

Uninstall the app and restart your phone

Usually, to do this, you need to hold your finger on the app icon and tap Uninstall. After that, switch off and switch on your phone. Next, download the app again from the app shop.

Check your internet connection

Try opening a few websites through your phone's browser - this way you'll make sure the internet is there.

Try logging in from another phone

If you can get in, there's probably something wrong with your phone. Make sure you follow all the instructions or contact a knowledgeable friend or service centre.

Look for the answer on the internet

If you're not sure exactly how to do the above steps on your phone, Google it - it's easier and quicker than contacting tech support.

Think about what could have gone wrong

Think back to the last time you successfully logged into the app and what changed after that. It could be a matter of your phone, network or account settings.

Give as much information as possible when contacting

When contacting tech support, please specify your phone model, OS version, application version (Settings > Lowest), whether you can log in on other phones and via bilderlings.com
