Exactly the app crashes when no internet connection, this is the log.

@zoobibackups it is not a crash it is just a console.error message which wont be displayed in release build.

Hi, as @haresh4d said, the message showed up when you handle ad load error with console.error.
You can write your own code to handle error.

i put this in try catch but no error log in the catch, seems that the error is not handeled by this package. console.error show nothing

tryCatch gives nothing in the catch.
And its own error handling also not working

[zoobibackups]

And why this issue is closed, have you provide any solution to it????

[wjaykim]

You can handle error not through try catch block, but using the adLoadError value of useAppOpenAd. If the error occurs while loading ad, the adLoadError value will be set, (was undefined before error occurs), then you can skip showing ad. That is because this library does not "throws" error but providing error info through hook returns. You can read documentation.

[haresh4d]

@zoobibackups use the latest version of library. It doesnt show any error there.
