When syncing the device and it is not completing the process, there could be an issue with memory or internet connection. So you should do the following on the device
- Close SelBuk and all other apps open
- Turn your device off for a few seconds
- Once you have your device active, make sure that you have internet connection
- Login just at SelBuk
- Try to sync (More > Sync > Sync now > Continue)
- Keep in mind that the device should sync not do a restore data from the cloud. If it is so, cancel and send an email to support@selbuk.com
