For some reason I never received beta rewards.

No one did,
but it might be a thing when this maintenance finishes today. March 31st is when they've told us. Keep an eye on the twitter or website front page for updates.
Since the OBT started, there was a message when you first logged in that CBT rewards would be distributed on March 31, 2020. Someone asked about it on Twitter and also received the response of March 31, 2020. If you read the CBT article on the main website, it says the CBT rewards will be given out at the time of "official release (date: TBA)"
