Mobile Development Kit Client - Error with Odata metadata on app update

Hello experts,

We are trying to get a MDK app running that accesses an OData service on our SAP back-end using mobile services in Cloud Foundry. So, we connected our CF account to the cloud connector and created a destination for our back-end in the CF also.

In Mobile services we created a Hybrid App and connected it to our OData service, see steps below:

When I ping or test the OData service it returns no errors.

At this point I have the feeling that my configuration on Mobile Services side is quite ok. We followed the steps on the tutorials for MDK, so the NEO instance has a destination that points towards the mobile-services on CF. We then follow the steps in following tutorial:

When we then open the app on the mobile phone we get following issue:

Any idea what might be causing this?

Thanks in advance!

Kind regards,

Robin
