Hi there! I see you’re having trouble reading messages on Nextdoor because you get a white screen. I want to help you get that sorted out. Just to clarify, when you say "white scy," do you mean the screen goes completely white or blank when you try to open your messages? Also, is this happening only with messages or other parts of the app too?

Meanwhile, here are some initial steps we can try on your iPhone (iOS 15.8.3):

1. Close the Nextdoor app completely (swipe it off from your app switcher) and then reopen it.
2. Make sure your Nextdoor app is updated to the latest version available in the App Store.
3. Restart your iPhone, which can help clear temporary glitches.
4. If you experience the white screen just when opening messages, try signing out of Nextdoor and signing back in:
- Open the Nextdoor app
- Tap on the menu (usually three horizontal lines)
- Scroll down and select "Log Out"
- Then log back in with your credentials.

Let’s start with those. If it still shows a white screen when you open messages, I can guide you through clearing the app cache or reinstalling the app. Let me know how it goes and if there’s anything else you noticed before this started happening!
