i have a question about the Test App performance. I shared my app as test app and downloaded it with the QR code. Is it possible the performance from the app would be better when I download the App from the App Store / Google Store ? Sometimes for example when the Sign up Screen is opening some stuff is faster with loading.
Native iOS apps are usually faster than PWAs (webapps) and previewers.
Native Android app performance may depend on the phone model - for the cheaper phones it’s not very fast.
