Hi there! I see you're having trouble signing into the Chewy app because the sign-in page keeps refreshing continuously. That certainly makes accessing your account tricky. To help you better, could you tell me if this happens right after you enter your login information or immediately when you open the sign-in page?

In the meantime, here are some straightforward steps you can try on your iPhone with iOS 18.6:

1. Close and Reopen the App
Fully close the Chewy app (swipe it away from the app switcher) and then open it again to see if the issue persists.

2. Update the App
Check the App Store for any available updates for the Chewy app. Running the latest version ensures bugs are fixed.

3. Restart Your iPhone
Sometimes a quick restart helps clear temporary glitches.

4. Clear App Cache (If App Offers This Option)
While iOS apps don't allow manual cache clearing, reinstalling the app does:
- Delete the Chewy app from your device.
- Restart your iPhone.
- Download and install the Chewy app again.

5. Check Internet Connection
Make sure your Wi-Fi or mobile data is stable and working properly.

6. Try Signing in on a Different Network
Sometimes network restrictions cause loading issues. Switching networks can help test this.

If after these steps the sign-in page still reloads continuously, the issue could be deeper, possibly related to your account or the app itself glitching on iOS 18.6. In that case, I can help escalate this or look into more advanced fixes.

Does the problem happen only on Wi-Fi or cellular data as well? And have you noticed if this started recently or after an update?

Let me know so I can assist you better!
