Every time you open your app it is a good idea to synchronize your app with your database. This is how you do it:
- Open your app
- Open the settings menu by pressing the top left button
- Press: Synchronize
- A blue slider will then show the progress in the top of the app. If it goes all the way to 100% then your app is synchronized with your database
If you have problems synchronizing you can go to the synchronization troubleshooting.
