Hi there! I understand you're having trouble with the Dairy Queen app not keeping you signed in, so you have to log in every time you open it. Let’s work through this together.

To start, can you tell me if this issue happens every time you close the app completely, or just when you switch away and come back? Also, have you recently updated the app or your iOS version?

Meanwhile, here are some initial steps we can try to fix this sign-in persistence issue on your iPhone running iOS 18.6.2:

1. Update the Dairy Queen App: Open the App Store, tap your profile icon at the top right, and scroll to see if the Dairy Queen app has an available update. If yes, update it.

2. Check App Permissions: Go to your iPhone Settings > Dairy Queen app. Ensure it has the necessary permissions, especially for Background App Refresh. This setting helps apps stay active and maintain sessions.

3. Enable ‘Keep Me Signed In’ Option: When signing in, look for a checkbox or toggle that says "Keep me signed in" or something similar. Ensure it’s enabled.

4. Check Network Connection: Sometimes, unstable internet can cause login sessions to reset. Try connecting via Wi-Fi or cellular data and see if the issue persists.

5. Clear Cache / Reinstall the App: Since iOS doesn’t have a direct cache clear option, deleting and reinstalling the Dairy Queen app can reset stored data and fix sign-in bugs.

If you’ve tried any of these already, let me know which ones so we don’t repeat steps. If the problem remains, there might be an account-related issue or a server-side problem to investigate further.

Does this make sense so far? Would you like me to guide you through any of these steps?
