Is anybody else getting a white screen when testing their barcode scanner component? Do you need to download the app in order to test? ---

You shouldn’t need to download the app itself but it may help to make sure your Thunkable Live app is the latest version. Hope that works! Albert ---

Hi there, We discovered there is an issue with some of the newer iPhones with iOS 13 when using the Thunkable companion. Here is the link to a newer version of the [Thunkable Live on Apple](https://testflight.apple.com/join/7rBLpV07). It should address your issue. Please download it and let us know if it works for you. Apologies for the inconvenience - Albert ---

I tested that Testflight app (your link) with a barcode app on iphone SE and ipad both with IOS 12.4 Works perfectly. ---
