Have you tried debugging your app to understand where the loop is?
- IMHO, this does not seem to be platform issue, if so lot of people would have complained about it
- So, either there could be a widget that is tracking the Browser back button behavior and some custom logic written is looping
- Or something weird is happening in the application which you can first debug from your side
- If you are sure, that it is a platform issue, you can file a bug to Mendix Support with scenario’s
