Expo publish and build issue

Hello, everyone.
I’ve an issue on publishing and building the app.
I am new to expo.
My app works very well on development mode.
But it’s not works after publish. The apk built has same issue.
My app calls web api for display data. But it seems to be no result.
How to debug published app? And then what should I do?
I’m very confusing. I’ve googled for a long time.
Please help me.
