The US government is forcing Google and Apple to share push notification data with them. Even if the content is not sent, the metadata alone can let them know who you are talking to and when using metadata correlation.
Signal push notifications don’t contain any useful plain text data (no content, no information about who sent you a message). AFAIK the only thing you would be leaking is that you received a message on signal, and frankly that metadata is probably going to be leaked to the US government regardless of your use of push notifications.
They can tell you connect to AWS when the Signal app fetches messages after a notification, they need to be able to peek into Amazon’s servers to see you’re connecting specifically to Signal

How?
Because your ISP and cell phone provider can tell you’re connecting to signal.

it’s not the content in the noti, it’s where your phone was connected when it received it
I mean… if you need to be worried about that, you really shouldn’t have a phone on you.
They get that from the carrier already
