Android production build splash screen hangs a really long time (more than set by fallbackToCacheTimeout)

See original GitHub issue

As suggested by @brentvatne and @tevonsb in #10463 I report this bug I have been having lately.

🐛 Bug Report

Summary of Issue

Android production build splash screen hangs a really long time (more than set by fallbackToCacheTimeout). It does come through - but it takes a couple of minutes.

Reproducible Demo

🍀 Luckily 🍀 this an open source project so the entire code and branch where I attempt to fix it can be found here

https://github.com/Norfeldt/MedBlockChain/tree/fix-loading-time

Steps to Reproduce

  1. Make an android build
  2. install it on a android device (android version 6.0) - I’m using an “old” Honor 7
  3. Enable developer mode
  4. plug in a usb cable to a computer with adb installed
  5. Do the following in the terminal 👇
$ expo publish
- Expo SDK: 39.0.0
- Release channel: default

Expected Behavior vs Actual Behavior

Wouldn’t have expected all of these warnings/errors and that it would have waiting max of what is stated in the app.json

I found out that this was because I had to change the QR Code react native library to something that renders really slow (https://www.npmjs.com/package/react-native-custom-qr-codes-expo). Changed it to one that is much faster and now everything is butter smooth.
