Sorry to hear it. However, once you've had a reset on your account you cannot re-earn those achievements on that account. If you want to earn those achievements again you'll need to create a new profile.

Has anyone started to see their achievements and activities? My smart glass app is blanked out and I've double checked the settings on all devices :/

I have the same problem. Going to daily challenge, click on a game, and I don't see the advertisement at all - it's just goes blank/all white.

All you need to do is press/hold down on the d pad and you will see a blanked 4th character slot that's where you go for the online when it launch's.
