Hi! I see you're having trouble logging into your Topps account on your iPhone with iOS 18.7. Let’s get this sorted out together.

First, just to make sure—are you entering your email and password exactly as you registered them? Even a small typo can prevent login. If you recently updated your email address, please try using the new one associated with your Topps account.

Here’s a step-by-step approach for you:

1. Double-check your email address and password for accuracy, paying attention to letter case and any extra spaces.
2. If you’ve forgotten your password, you can reset it by visiting the Topps password reset page: https://play.toppsapps.com/reset-password. Enter your username, and they will send a verification code to your registered email.
3. Make sure your app is updated to the latest version from the App Store, just to avoid any compatibility problems.
4. Try logging in again after resetting the password or confirming your email details.

If you’re still unable to log in after these steps, please let me know if you see any specific error messages. Sometimes certain log-in issues need in-depth support from the Topps team, and I can guide you on how to contact them directly from your registered email address for security reasons.

Are you able to try these steps and tell me what happens? That way I can assist you better!
