Proving Grounds + event bug

I recently just bought the episode + pass to that I could get more shards in the proving grounds+ event that started just this month. It’s worked for me in the past, however yesterday when I bought the episode + pass, I went into the proving grounds + event just to find all of the characters still locked and I was unable to participate in the event and spent my money for nothing… I tried redownloading the game off the App Store and everything, but no luck. please help!!
