I did not get the anniversary rewards, it might be possible that I accidentaly deleted them (if thats possible). I also heard from others that they didnt receive it.
Same here, I only got it on the alt, the main character still without.
We're aware of this issue and have added it to the "Known Issues" list for Patch 2. We will fix this in the coming days and you should automatically receive your rewards after that on all characters.
