You can try restoring your purchase if you have a Premium subscription but can only sing 5 songs for free. The reason behind the issue can be something else, so make sure to check the broader help article on the subject in this article.
The details of a completed purchase don't always make their way to us, which can cause the subscription to not show as active within the Singa service. This is more likely to happen with the App Store than with Google Play. Please see below for steps to restore the purchase on iOS and Android.
For subscriptions started via the Apple App Store:
Open the Singa app on your device.
Open your profile by tapping the profile picture/silhouette in the top right corner.
Find the "Subscription settings" section from the list.
Tap "Restore purchase."
For reference, you can check Apple's guide from here. If you can't restore your purchase and need to request a refund, please see Apple's instructions here.
For subscriptions started via the Google Play Store
Please note the menu system on Android devices might differ slightly depending on the manufacturer.
Open the Settings app on your device.
Tap "Applications," "Manage applications," or similar.
Tap Singa
Tap "Force close"
Open the Singa app normally.
Check if the Premium subscription is now active (e.g., the app's Profile menu does not mention "Free songs left: 5")
