New iOS 12.4 update may interfere with Push-to-talk applications and accessories

Posted on 2019-08-15 by AINA Marketing

The iOS 12.4 update for iPhone and iPad requires the majority of push-to-talk apps to be open and visible on the screen to be able to send PTT messages. In other words, messages may not be sent through the phone or Bluetooth speaker-microphone if the PTT application is running in the “background” (not visible on the screen). Therefore, we recommend not to update to this iOS version until you receive more information from your PTT application provider.
