Android ChatGPT app error after before tools/call

I’m debugging a ChatGPT MCP/App SDK app on Android.

On Android, invoking my app shows:

“An error has occurred. Please try again later.”

Server logs show:

• initialize: 200
• tools/list: 200
• resources/list: 200
• resources/read: 200
• then generic error
• no tools/call ever reaches my server

So the failure seems to happen inside ChatGPT Android before my tool handler runs.

Has anyone seen Android fail before tools/call?

This started happening for 2 of my apps, been trying to (vibe)fix it for the past 2 days but nothing.

The app works fine on browser or iOS.

Would greatly appreciate any help with this (I’mgoingabitinsane)
