😩 Works fine in dev with exp or expokit - published hangs on loading splash in exp ios+android, standalone ios+android

Published version of application hangs on application splash screen :weary:

Recently I upgraded to expo 27.0.0. :disappointed_relieved:

Everything was working great in dev for both android and ios, then I published.

The published version hangs on the loading splash. I have tested the published version on these devices:

  • Exp ios
  • Exp android
  • Expokit standalone ios
  • Expokit standalone android

I found some articles offering “fixes”. I followed their suggestions, but I suspect most of these are out of date.

Things I have tried:

Perhaps the issue here is a javascript error? I suspect it might be in .

My question: How can I debug this? How can I see any javascript errors that might be happening? I’m seeing nothing on the iOS Console, nor Android’s Logcat


Hi @lordfingle. The best way to debug this type of issue is to try reproducing the error in development. If you add --no-dev --minify flags to exp start that will mimic the published version. Then you can start adding logs and seeing where you app is hanging.

Thanks for the reply Jesse. I did see this advice elsewhere. “Unfortunately” ‘exp start --no-dev --minify’ doesn’t have the problem. :disappointed_relieved:

Instead I’ve been in a slow cycle of commenting stuff out and publishing.

It appears to me that the “Apploading” component might be the problem, although without logging I’m working blind here.

Ok, thanks for trying. If you create a How to create a Minimal, Reproducible Example - Help Center - Stack Overflow that has this issue we can take a look at it. Hard to say what might be wrong without seeing the code.

:woman_shrugging:I turns out I was able to “fix” the problem by deleting and re-installing the app.
