Feedback widget hybrid ios app

We are experiencing some trouble with setting up the feedback widget on ios 9+ Whenever we click the feedback button it seems to open an empty popup. At first I thought this was due to the ATS system of IOS but when you open the app in the browser everything seems to work as expected. Did anyone else ever encounter an issue like this?

In the MVP group we just had a discussion about this . Marcel Groeneweg mentioned that he is having problems on smartphones due to the Javascript that is used (so all credits to him for this). The feedback API does not support image uploads while the feedback widget does and uses this Javascript to do this. 

To my opinion a support ticket should be created. The feedback widget should also work on smartphones to my opinion.
