If your device is not completing an initial sync, there may be a number of reasons. Occasionally the sync may get jammed on a piece of data not coming down correctly. In this case the remedy is to delete the Cavanti mobile app, re-install and log in again.
If however your device is consistently failing you probably have a more serious problem. The most common cause is that your account may be too big, and your device is refusing to give us enough space in one lump to download your data. In this case, navigate on the mobile app to more > settings > App logs. Scroll to the bottom of the log, and tap 'email to Cavanti'. Then send us an email to support@cavanti.com and let us know your device is not completing initial sync, we can then reduce the number of historic sessions we send down to the device to reduce the size of your account and get it to sync successfully.
