hi,
i found the same issue, i use fb4.7 and package ios app.(doesn't use adt tool),if i don't add param -useLegacyAOT yes, the app will crash on phone.(with air15.0.328 beta).i found maybe Sound.play crash app.When i add -useLegacyAOT yes,it will run well,but package time is too long.
Someone can share some light about this issue?
