Audio Player and Audio Player/Recorder control doesn't work on iOS 12.2
The recent iOS 12.2 update changed the way media files are handled in the PhoneGap web view. In order for the UX Audio Player and Audio Player/Recorder controls to work with iOS 12.2, the iOS Media Playback Requires User Action property must be disabled in the PhoneGap configuration.
Beginning with Alpha Anywhere build 5771, the Media Playback Requires User Action property will be disabled by default.
To change this setting in existing projects, check the Show Advanced Options property in the PhoneGap App Builder Genie.
Then, uncheck the Media Playback Requires User Action option in the iOS Only settings.
