If you experience a technical problem, try to follow these steps.
- empty your device cache
- uninstall and download the app once more
- be sure to give the app all permissions
- keep your wifi connection always switched on (even without a network to connect to)
- keep your energy save mode OFF whilst using the app as this limits its performance
- do your check-in outdoors
- avoid jailbreak or unlocked root permissions
If this still does not solve your technical issue, please contact us, and provide us with as many details as possible about your issue.
