I know we can pass different sound formats in phaser3 to let browser choose the compatible format.
1. According to this this and this mp3 is supported in most of the major browsers. So is it wise choice to use only mp3 format? if not then which format should be used with mp3 to support wide range of browsers?
2. Does this issue with ios 9 that required user engagement to start audio playback is handled by Phaser 3? From documentation it looks like WebAudioSoundManager has unlock method to resolve this issue but I'm not quite sure.
