Tensorflow model.predict gives instant results in Android Emulator but stucks on Iphone/Ipad after deployed to Expo App

I’m totally new to Tensorflow, I’ve just trained a custom model in Teachable Machine and successfully made right predictions after loading the model in my React Native app.

let model = await tf.loadLayersModel(bundleResourceIO());

This predictions are really fast and accurate on Android Emulator. But after deployment of app the prediction part stucks without error and gives no result (on Iphone/Ipad).

I’ve tried to use tflite instead but had no success to load the .tflite file localy.

Tensorflow backend uses rn-webgl

What could be this huge difference of performance between environments ?
