If you are in charge of setting up the Mews Navigator, its important to note the following:

We aim to keep the app running as fast as possible, therefore we cache a lot of data on your device, so that it does not have to constantly load all of the data. This has a great impact on the speed of the application.

However this might be a little frustrating when you are setting up the application, because when you add content such as photos or services, the content will not immediately be visible.

How to fix this?

Simply delete the app from your phone, which will cause it to remove the content and cache. Then reinstall the app. When you log in, it will trigger a download of fresh data on the phone, which will include the photos and services you just added.
