I have web viewer in my app. I have issue to publish to ios. When I made the Tracking usage description as Blank, I have error as “Unexpected error occurred” and automatically close the app. If I enter the description in Tracking usage description, I have error as NSUserTrackingUsageDescription in App Privacy section, so I cannot forward to submit the app to ios. I do not use any Admob or location censor at all. Anyone know the solution for my case. ---

Do you require `Location Services` when using the `Web Viewer? If YES, then you have to supply enough information in the policy section. If NO, then **switch it OFF** from the `Web Viewer` property tab. **[Update]** I just reviewed the `Web Viewer` properties tab and it says **Android only** so this should not be the problem. ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/0/b/0bdc83f2995da1ecddd0f36b12bb25cf91337602.png) ---

I do not use the Location Services at all. Do you have any direction or advice to set up App policy to remove NSUserTrackingUsageDescription and submit for review? I set up app policy and submit several times, but the Apple rejected again. ---

Before submitting the app to App Store, if you are not using any of the components / services that can cause tracking then make sure you delete the default text in the tracking box in the project settings page in Thunkable. ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/7/b/7bf5365e6d9b7ba46d3268d65ab5da5068b56fb6.png) **[Update]** Remember that BLE, Maps, Push Notification and Location Sensors are all regarded as tracking components. ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/e/3/e3d93b30c95c78920dbaed427f2bc84098fc836f.png) ---

If I use the web viewer and leave Tracking Usage Description as blank, it give an error as “Unexpected error occoured” when I open the app. ---
