Published Android app doesn't open


I’ve published my app on Playstore yesterday :

When I touch the app icon in order to open it, nothing happens…

My Android phone is old (Huawei MATE Lite 2017), but other recent and updated apps work just fine on my phone.

Can you tell me how to solve this?

It opened on my end. Dude you have advertisements… after first question the advertisement appear and then quiz was never proceeded. I think this can be improved significantly.

How Did you get foreign language font? I thought custom fonts not supported

Ok thanks for your answer dude.

I’ll ask other people if theme list doesn’t show after ad.

I didn’t add any font, works fine naturally.
