Hi! I understand you're seeing a grey circle with a red spinning circle inside on your iPhone's Ibotta app after changing your password, and it never updates. Let's get this sorted out.

First, just to be clear: did the spinning red circle start immediately after you changed your Ibotta password? Are you connected to Wi-Fi or using mobile data? And have you tried closing and reopening the app since the password change?

Meanwhile, here are some steps that often help resolve this kind of loading issue on iOS devices:

1. Close and Reopen the App
- Swipe up from the bottom (or double-click the Home button if your iPhone has one) to open the app switcher.
- Find the Ibotta app and swipe it up to close it.
- Reopen the app and try logging in again.

2. Check Your Internet Connection
- Try toggling between Wi-Fi and cellular data to see if the app can connect properly. Sometimes switching networks helps the app refresh its connection.

3. Restart Your iPhone
- Press and hold the side button and volume button, then slide to power off.
- Turn your phone back on and try the app again.

4. Update the Ibotta App
- Go to the App Store, tap your profile picture, and scroll down to check if there’s an Ibotta update available. An outdated app might cause loading issues.

5. Clear App Cache via Reinstallation
- Since iOS doesn’t have a direct way to clear an app’s cache, deleting and reinstalling the app can help.
- Press and hold the Ibotta app icon, tap "Remove App," then "Delete App."
- Go to the App Store and reinstall it, then try logging in with your new password.

6. Default Browser Setting
- Sometimes Ibotta uses your device’s default browser for authentication. Check your iPhone's Settings > Safari (or your default browser) and ensure it’s set to a supported browser like Safari or Chrome.
- Try changing the default web browser in your iPhone settings to Safari if it's set to something else, then restart the Ibotta app.

If these steps still don’t let you get past the spinning red circle, it might be related to a backend issue or a problem with your account settings after the password change.

Would you please let me know which of these steps you’ve tried so far? That way, I can guide you better. Also, are you seeing any error messages besides the spinning circle?

Looking forward to helping you get back into your account!
