Update 21.5.2018 @9:05
Google and Huawei are working on a fix, but in the mean time there's a work around that might work. Go to Settings > Applications > Google Play Services and choose remove the updates. Reboot your smart phone and reinstall the Google Play Services from the Play store.
We've noticed an issue with our Snowfox application run on some of the Huawei's Android devices. Due to this problem, the application won't start. Recent updates to Google's map service is affecting not only Snowfox application, but many other applications which use Google maps. It seems that only Huawei devices are affected.
We apologize the inconvenience.
