Minimal reproducible example

Summary

Showcase expo-image is broken on some blurhashes, compared with react-native-blurhash side by side.

This is observed only after using together with expo version after 48.0.0-beta.2, basically all the GA versions would fail some blurhashes.

@xmflsct - are you noticing this on ios, android, or both?

@brentvatne oh forgot to mention, iOS only. Android is working perfectly fine.

Exact same problem here with ios and expo sdk48.
Working properly on android.

I am having the same issue, only iOS. Expo 48, expo go.

I think its the characters, this doesnt work: L5NTzf}YM{n$0.#loLoL3Y9tRjjY

But i removed some chars, replaced the . and # to 0 and this worked: L5NTzf}YM{n$000loLoL3Y9tRjjY

Here's another one that breaks: e47BApj[00ayRjD%azayj[?I00j[_4ayxu_3j[WBay4nt7ayofofM{

Also confirming that it is only broken on iOS - Android; and Web are both working fine. Expo SDK 48.0.2.

I've just published expo@48.0.7 that should fix this issue. I would really appreciate if someone could try it out and confirm whether it works 🙂

Thank you @tsapeta! I can confirm it is now working correctly for blurhashes.
