Facebook Save Issue
If you cannot upload your save to your Facebook via cloud saving (continuously getting an error) from the options menu, go to settings and clear the cache on Pixel Car Racer (no, this doesn't remove your save.)and try again. This should resolve your problem. In the rare case this doesn't fix it, please copy and paste the error code or screenshot it and send it to the support/troubleshooting section of https://www.pixelcarracers.com/.
