Chevrolet Camaro

When I open up the Chevrolet Camaro special event the screen turns black screen except the top buttons for back and home and such except they don’t do anything when you click on them and the game stays black.  I tried refreshing the game. I tried redownloading the game.  I also tried turning my iPhone off and back on yet the problem persists when trying to open up the Camaro special event.  The rest of the game works fine.  The black screen goes away when the game is refreshed but it’s sad that I have a slot taken up in my special events by this bug please help
