App won’t open ?

I have an IPhone 8 and took the update. I went to open the app and it just won’t open. The EA Sports front page opens then it blinks back to the app icon. I loved playing this gam and now it doesn’t open. I closed all open pages, rebooted my phone etc... NO LOVE. YOU DEVELOPERS NEED TO FIX THIS!!!
