messages "leaking" through ship's free App onboard

[Markanddonna]

We recently sailed with MSC, and there were a few instances where we received weather reports and messages from other apps. We visited the internet crew, who told us that we had everything set correctly and that sometimes things "leak" through their app. 

 

Has anyone else experienced this, or is it just MSC's infamous technology?

Never happened with us with RCCL or Celebrity.

OK, need to get technical here.

Both Apple and Google have a service to pop up notifications on your phone. In order to get a notification on your phone, the app/service/etc needs to be able to communicate with the notifier service to then send the notification to your phone. It's possible the ship had the ports these services use open for all devices.
