Tablet is fixed potret mode, even when holding in landscape mode (locally on the Mendix Mobile app)

Hi I notice a strange behaviour when running our tablet app locally and mirroring on the Mendix Mobile app on a iPad (all updated). When I run the app locally, and scan the QR code to run the app on the Mendix Mobile app, it opens but it is fixed on portret mode. While viewing ipad version in browser is on landscape mode. So I expect that the app must be also in landscape mode, but that isnt the case. I know that when you have a phonegapp build you can set up a preferred/fixed mode (landscape or potret), so could it be that the Mendix Mobile/Developer app has a fixed potret mode on their builds so that I am not seeing our app in landscape (seems me strange for developing purposes). Same situation with the developer app. So anyone an idea how I can see the local tablet app in landscape? BTW: this is a poc, free app, that should not be impacting the whole stuff I think.
