So, I recently synced my new Google + account to my phone. Everything is going smoothly, I selected it as the account to use in the Google Play Store...but...whenever I try to download an app from Google Play, a message pops up that says "Authentication Required--you must sign into your Google account." So I go to my Google + settings and choose to sign in with my account, but every time it says "Couldn't connect to the server." Why am I having this problem? I deleted a lot of apps that were taking up space and now I can't re-install anything because I can't sign into my Google account (although somehow it still synced, argh). And tbh I have no idea what the "server" is; I have perfect service and wi-fi so I don't know why my phone won't connect. Help!!!
