Nightmare morning. Woke up for the fact that my app in app store is crashing on opening. Yesterday submitted improvements to the app (react-native).

Tested locally on simulator and also on real machine by react-natives --variant Release. Worked ok. But now when I build it with xcode and sent it to app store, it's no longer working at all =/.

Im losing users by every minute. Was able to immediately make a hotfix, but apple has not taken any hurry in reviewing it. Also it's not possible to revert previous version in app store, I just have to submit a new version that will be reviewed. I even called them and they promised to hurry but nothing's happened and it's been like 4-5 hours already.

I got so bad luck because usually in review they test the app, but now they didn't, and this time it didn't work at all. And I thought that testing it by react-natives --variant release mode would be enough, but apparently theres something different when you build and archive it with xcode. I feel my app is doomed now, many of the users might abandon it completely =/.

If I learned something it is that always try to test the last modified version of the app. Even if the modification seems small. Don't trust react-natives --variant release for testing an ios app.
