I am ready to give up on my Nexus. When trying to download magazines in the Play store I get: Error retrieving info from the server (DF-BPA-21)... This has been happening during searches and purchases. I followed the instructions in other posts about clearing cache / data of the play store apps. I even did a Factory Data Reset and still have the same issue. Any other suggestions? If I cannot download stuff in the Play store then I am not happy with this device.
