Hi,
I noticed this in the release notes:
- Known Issue (not resolved): SimpleJson does not serialize correctly when using the Player Setting "Scritping Backend" option: "Mono2x". Until this is fixed, please use "IL2CPP" if possible.
IL2CPP isn't officially supported for Android builds, as of Unity 5.3.4p1.
I am curious what priority this fix has, since it sounds like a blocking issue for Android games. Or maybe it's not as bad as it sounds. :)
Cheers,
Jason
