I use UE4 and wwise to build my ios game. When other app notification message popup, my game will stuck twice.
(1) After I remove wwise, the problem vanish.
(2) when I disable other app sound notification, the problem vanish.
(3) I try to set "EAkAudioSessionCategory AudioSessionCategory = EAkAudioSessionCategory::PlayAndRecord;" in AkIOSInitializationSettings.h，my game never stuck and sound vanish. According to IOS ducument, default "Ambient" also will avoid this problem(Why wwise is not valid?). Besides, I try to set config file(Config/DefaultGame.ini) With "AudioSession=(AudioSessionCategory=PlayAndRecord,AudioSessionCategoryOptions=2,AudioSessionMode=Default)", It is not valid.
UE4 Version: 4.24.1
WWise Version：2019.1.10
