Resolve Pro-Version & Account Issues

On this page, you'll find help with the most common issues related to your account and your Pro-Version.

‍After purchase, your Pro-Version is automatically linked to your account in the app.This means you can use it on all your devices as long as you're signed in with the same account.Your training data is also synced through this account.

Pro-Version no longer active

Your subscription is permanently linked to your account and can't be removed manually.

If your Pro-Version suddenly appears inactive, please follow these steps:

Check your account

Make sure you're signed in with the correct account – the one you used to purchase the Pro-Version. You can see your account’s email address at the top of the app settings.

Ensure you log in using the same method as when you made the purchase (e.g., password, Google, Apple). Only then can your subscription be recognized correctly.

Check your subscription status

Verify that your subscription is still active. Depending on your device, you can check this in the Apple App Store or the Google Play Store.

If your subscription has expired, it won’t be recognized – even if you're signed in with the correct account.

Restore your purchase

If your subscription still shows as active in the store, you can manually restore it:

1. Open the app on your smartphone
2. Go to [ICON:settings] Settings
3. Tap [ICON:loyalty] Restore purchases
4. Follow the instructions in the app

This will try to re-link your store subscription to your current account.

Error message: RECEIPT_ALREADY_IN_USE or ReceiptAlreadyInUse

This message means you are signed in with a different account than the one linked to the subscription.

Please do the following:

1. Double-check the email address of the currently signed-in account (visible in app settings)
2. Ensure you’re using the correct sign-in method (Google, Apple, password, etc.)
3. Check “Sign in with Apple”
   
   1. On your iPhone or iPad, go to Settings > [your name] > Sign in with Apple.
   2. Look for The Mantrailing App in the list.
   3. If the app appears there, you originally signed up using “Sign in with Apple.”
   4. In this case, make sure to log in to the app using “Sign in with Apple” (not with email/password or Google).

Contact support if nothing works

If you still can’t activate your subscription after trying everything, please send me a message – directly from within the app.
Make sure to use the built-in support option so your account details are included automatically.

Depending on your platform, please also provide the following information:

• iOS users: A screenshot of the error code shown when trying to restore the subscription
• Android users: The Google account email address used for the subscription or the subscription number (starts with GPA), which you’ll find in your Google purchase confirmation

To contact support, go to [ICON:settings] Settings > [ICON:help_center] Help in the app. After a few seconds, a contact button will appear at the bottom of the screen.

Training data is missing

Your training data is synced to your account. If it suddenly disappears in the app or parts of your documentation are missing, it usually means that you are signed in with a different account or have switched accounts in the past.

The app uses your email address to identify your account and synchronize your data. If you start using another email address to sign in, your data will not be synchronized.

Please check the email address of the account you are currently signed in with (visible in the app settings) and your login method – for example, “Sign in with Apple” can generate a new, random email address. In such cases, your data cannot be synced properly.

If the wrong account is used, simply log out and sign in again with the correct one. As soon as you are logged in with the right account, all your data will reappear immediately.
