Please report the bug through the Shake & Report feature. Any other way of reporting technical issues will be slower and less effective in helping us fix it.
1. Go to the QuizUp Tab
2. Tap the Settings (the two gears) in the top left corner
3. Tap 'Privacy'
4. Once in 'Privacy' tap the slider next to 'Shake to send feedback' to enable Shake & Report
5. Shake your device and tap 'Report technical issue' to send us an email. Please describe your issue in as detailed a manner as possible.
Known issue on iOS: If you don't get the Send feedback option when you shake your device, you need to enable the native Mail client (the Mail app by Apple). You can currently only send feedback through the Mail app.
Known issue on Android 6.0: Please go to settings -> Apps -> Gmail -> Permissions and enable the "Storage" permission manually so we can get the attached info.
Here's a GIF that explains how you can enable it :-)
