Anyone else? iOS app can’t load iPhone Voice Memo (.m4a) files

..endless spinner, no error message in the ChatGPT iOS app. They upload successfully but never load — they just show a spinning placeholder. I'll

This happens even when:

  • The memo is correctly exported to Files
  • The file uploads without an error
  • Other audio formats work
  • The same file loads fine when converted to MP3 on a computer

The assistant repeatedly tries to troubleshoot (folders, export steps, etc.), but doesn’t know that this is a client-side decoding limitation in the iOS app. There’s no clear error message, so both the user and the model waste time.

Feature requests:

  1. Show a clear error if an audio codec isn’t supported
  2. Add reliable support for iOS Voice Memo .m4a files
  3. Let the assistant detect or ask about the user’s environment earlier
