Zetamac - Fast Math World Championship

I'm using zetamac for few months now and it was working just fine, but since i have factory reset my phone and reinstalled it after the reset it has stopped showing the full question. Like 2+ =? Or 5* =? It doesn't show what number comes after the symbol. Kindly fix this. PS : i have already tried uninstaling and reinstalling the app 2 times but nothing worked.

אפליקציה מעולה, מאוד שימושית משחק עם הילדים

Nice game! Excellent for brain training 💪
