I've made app Android and IOs, and everything works on my Android and IPhone. But once IOs app is on the appstore, some users have a problem. App launch less than 1 second and close immediatly. I don't have access to this phones. So, no log, I have nothing. Can someone help me ?

All is up to date.

Thx.

I've tried everything I can.

I have experienced same issue in my apps too and there can be multiple factors for it. OS version, internet, RAM and thousands of others. I would recommend integrating Firebase crashlytics in your app, it will increase your app size but there's always a tradeoff.

When you mean that you run it normally in your Android and iPhone, do you mean via your IDE? if yes, try to run the app with the --release flag from your IDE. I think that every app is compiled differently when its upload in the store. Running the app on your IDE with the flag --release will simulate this compilation and you will manage to find the error. I think Something might be there.

Which flutter version are you using?
