There are a few different issues that might cause the synchronization issues:
1. Poor internet connection
Please make sure that your device has a solid connection to the internet.
2. The Task is not shown because of filters
If you set the incorrect filters or too many of them, they might filter out all the tasks from the device:
(In this example, the indicator 5 indicates that there are 5 filters turned on)
3. Download the newest APP version
If the App User has an old version of the app, this might create additional synchronization issues. Please make sure to always have the newest app version from Google Play.
You can also set up automatic application updates, here's how.
4. Restart the application
Also, sometimes the application has to be restarted, so the new information would be loaded. Please turn off the application completely, and remove it from the apps working in the background.
5. Other Synchronization issues
In such case, if the other 4 solutions do not apply, please contact customer support, and we will do our best to help you as soon as possible.
