Why am I unable to download free apps but asking me to pay for it suddenly

There could be a few reasons why you're experiencing issues with free apps appearing as paid. Here are some possible explanations:

1. **Temporary Glitch:** Sometimes, app stores may have temporary glitches that cause free apps to appear as paid. Try refreshing the app store or restarting your device to see if the issue resolves itself.

2. **Account Issue:** Check if you're signed in to the correct Apple ID or Google account. If you're using a family sharing plan, it's possible that someone in your family has made changes to app purchase settings.

3. **Region Restrictions:** The availability of free apps can vary by region. If you've recently changed your location settings, this could affect which apps are available for free in your region.

4. **App Price Changes:** App developers have the ability to change their app's pricing. Sometimes, a previously free app may start charging for downloads or introduce in-app purchases.

5. **In-App Purchases:** Some apps offer free downloads but require in-app purchases to unlock certain features or content. Make sure you're not confusing these in-app purchases with the cost of downloading the app itself.

6. **Compatibility Issues:** If you're using an older device or operating system, some apps may no longer be available for free or may require an update to work correctly.

If none of these explanations apply, it's a good idea to contact the app store's customer support for further assistance in resolving the issue. They can provide specific guidance based on your account and device details.

Is there a price showing on the free app? It may be that it has a trial of the paid version & a card would be required for that.

I’ve found that even free apps will require a payment method adding to your account as proof of age.
