Hi! I see you're having an issue where the Thrift Savings Plan app on your iPhone shows a blank white screen that freezes and doesn't let you do anything. Let’s work together to get this fixed.

A few quick questions to better understand the situation:
- When did this start happening?
- Did this issue begin right after an app update or iOS update?
- Have you tried closing the app completely and reopening it?
- Also, is your iPhone connected to Wi-Fi or using cellular data when this happens?

Meanwhile, here’s a step-by-step approach you can try on your iPhone (iOS 18.6):

1. Force close the app:
- Swipe up from the bottom of the screen and pause in the middle (if you have a Face ID device).
- Find the TSP app preview and swipe it up to close it totally. Then open the app again.

2. Restart your iPhone:
- Press and hold either volume button and the side button until you see the power off slider.
- Slide to power off, wait 30 seconds, then hold the side button to turn it back on.

3. Check for app updates:
- Open the App Store, tap your profile icon on top right, scroll and see if the Thrift Savings Plan app has an update available. If yes, tap Update.

4. Check your internet connection:
- Try switching between Wi-Fi and cellular data to see if the issue is related to connectivity.

5. Reinstall the app:
- Tap and hold the app icon, select Remove App, then delete it.
- Go to the App Store, search for "Thrift Savings Plan," and reinstall it.

If the issue persists after these steps, it might stem from an account access problem or a temporary issue on TSP’s side. There are no known widespread outages right now, so it’s likely local to your device or app settings1 3.

Please try these steps in order and let me know which ones you’ve already attempted or if anything changes. We’ll figure it out together!

Are you okay with trying these now?
