[UE4] Sound being paused during a level change

Question

Hello,

In our game realised with unreal, we need to play music during level loading without using level streaming. It was correctly working with unreal 4.16 but we had to upgrade to 4.18. Since, the music is slightly cut during the level loading when we run our project in the editor but much longer when we run it on Android. I was hoping finding someone who could explain me why (we also contacted Epic but they told us to ask the question here), maybe the Wwise plugin changed since 4.16 ? Is there a workaround ?
