PayPal went on a little vacation from the Windows Phone Store earlier this week, but we are happy to say it is back today. The app had disappeared from the Store for Windows Phone 8 devices, but not WP7 devices. The reason for the disappearance was the app was crashing on the Lumia 920 and HTC 8X. They have fixed that issue and now the app is running fine. Kudos to PayPal for seeing a problem and halting any more downloads until it was fixed.
