I have an LG G2 with Android 4.4.2, and all of a sudden I cannot download apps or updates on the Google Play store. In my settings > mobile data menu, the "limit mobile data usage" option is NOT checked, and the problem persists on both 3G and 4G/LTE. My data limit has not been reached (I don't even think I have one).

In the settings > mobile data > google play store menu, the "restrict background data" option is NOT checked either. In the Google Play app settings menu, the "Auto-update apps" is set to wifi-only, but that's how I want it. The problem is when I manually try to download/update, so that shouldn't be the problem.

My Google Play build version is 5.4.12, if that helps...

Wi-fi downloads are just peachy though.
