Autofill content type in PowerApps sharepoint form

[cillesoe]

Hi, fellow PowerApp-people!
I have an issue that I can't wrap my head around any longer. I feel like I have tried everything, so now I have to ask for help here. 

I need to auto-populate the "Content-type" field the app is getting from SharePoint. I have tried a collection, and I have also tried with the url parameter that retrieves the ID of the content type. The parameter-workaround works, it does auto-populate the content-type field, however, not in a "NewForm"-mode. It instead automatically shows the first list-item from the list, with ID "1", and in edit-mode, and also updates the list item with ID "1" instead of creating a new.

Does anyone have an idea how I can solve this, or has anyone had similar issues?

Best regards,

Cecilie
