[cinzianicoletti]

Please provide all the information requested. Issues that do not follow this format are likely to stall.

Description

The application correctly displays all the alerts and toast messages in the debugging phase. The moment the build is built all the messages disappear.

React Native version:

  Yarn: 1.22.4 - ~/.yarn/bin/yarn
  npm: 6.13.7 - /usr/local/bin/npm

Expected Results

That alerts are shown in build mode.

I attach the package.json to see if there are any known incompatibilities:

Can you share more information. Which alert are you using? Is it react native's alert or javascript's alert method?

The problem disappeared when I switched from version 59.9 of React Native to 60.0. 🎉 But I couldn't find any solution.

Hi Folks,
unupdated .main.jsbundle in bundle copy resources caused this issue.
ref: #29356
it got fixed & works fine!!

The problem disappeared when I switched from version 59.9 of React Native to 60.0. tada But I couldn't find any solution.

@nicolettinzia if the problem disappeared, then could you please close this issue? We have 1.1k open issues and contributors invest months to read, triage, troubleshoot and then publish fixes for each issue...because there are very large amount of discussions...

Closing the issue if does not reproduce anymore on latest release really helps. Thanks

I had the same problem, but my error was my fault. I passed an empty object {} to the buttons parameter of the Alert.alert() function. I changed it to undefined and now it works as expected.
