App does not open past launch screen since 3.10 App Store update

[galexite]

Describe the bug
Since updating the app to 3.10 from the App Store, I can no longer open the app on my iPhone XR (model number MRY52B/A) running iOS 14.0.

The app hangs on the launch screen, as in the following screenshot:

This occurs even after removing the app from the multitasking menu and attempting to re-open the app from the home screen, or from Settings app's 'View Exposures in App' hyperlink.

To Reproduce
Steps to reproduce the behavior:

1. Update app from App Store to version 3.10.
2. Go to Home Screen
3. Click on NHS COVID-19 app icon
4. Wait indefinitely for app to pass launch screen.

Expected behavior
The app opens and proceeds to the first view controller as normal.

Smartphone (please complete the following information):

• Device: iPhone XR
• OS: iOS 14.0
• App Version: 3.10

After upgrading to iOS 14.2, the app appears to work normally.

Same issue - iPhone XR, iOS 14.1
Additionally, my installation has lost the app icon, reverting to the Xcode default app icon.

The app stopped working in my wife's iPhone 11 with iOS 14.1. Updating to 14.2 solved the issue.

Thanks for your interest in the NHS Covid-19 project. This issue affected a small number of iOS users. Upgrading to the latest version of the app should fix the problem in most cases. For more details please see the FAQ at https://faq.covid19.nhs.uk/article/KA-01349/en-us @TimothyChilvers - thanks for the information about the app icon - I will pass this on to the developers.
