There could be multiple reasons behind not seeing the Feature Requests mobile view as we'll see below.
Placement in Code:
If the page is triggered inside the onCreate method of a view or activity (in Android), it may not appear.
Solution: Move the method inside a button action instead.
SDK Integration Issues:
If the SDK isn’t integrated correctly, the Feature Requests page won’t load. You can check this article for more info on integration per platform.
Plan Limitations:
If the SDK isn’t integrated correctly, the Feature Requests page won’t load.
Solution: Check your Instabug plan to ensure it includes this feature.
Lastly, make sure that feature requests are enabled by following the instructions here. It should be enabled by default; however, disabling feature requests will prevent the page from displaying even when manually invoked.
