If you are having trouble claiming free credits, it may help to clear the cache of your mobile device's default browser. The browser launches when you tap on a free credits link, and clearing the cache can help the link load properly.
On iOS devices, the default browser is Safari. These simple steps will clear the Safari cache:
- Launch the Settings app on your device.
- Scroll down and choose Safari in the left hand menu.
- Scroll down and tap Clear History and Website Data.
- Tap to confirm the action when prompted.
After clearing your cache, try again to collect the free credits.
