Hi! I understand you're having trouble logging into the Cogeco My Account app on your iPhone, and it keeps bringing you back to the sign-in page. Let's work through this together.

First, could you confirm if you’ve already tried these basic steps?

1. Double-check your username and password to make sure they’re correct.
2. Close the app completely and reopen it.
3. Restart your iPhone.
4. Ensure your iPhone has a stable internet connection (Wi-Fi or cellular).
5. If you are using the app, try logging in through Safari browser on your iPhone at https://myaccount.cogeco.ca/ to see if it's app-specific.

If you’ve tried those and the issue continues, here are some more steps to try:

1. Clear the app’s cache (if possible): On iOS apps, this usually means deleting and reinstalling the app. Try deleting the Cogeco My Account app and then reinstalling it from the App Store.
2. Check for app updates: Ensure your app is updated to the latest version compatible with iOS 18.6.
3. Check for any Cogeco service outages: Sometimes login issues happen if there is an outage affecting My Account services. You can see if there’s a known issue by visiting Cogeco’s status page or searching recent user reports.
4. Reset network settings on your iPhone: This can solve some odd network-related login loops. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. (You’ll need to re-enter Wi-Fi passwords afterward.)

If none of these work, the problem might be on Cogeco’s side, possibly an account-related or server issue.

Could you let me know if you see any specific error messages when the login fails? Also, have you recently changed your password or account details?

That will help me guide you specifically. Let me know!
