What value does it have?
The payload of Signal's push notifications should have roughly the same length every time as they are only used to wake up the app. The time I receive a push notification doesn't depend on me, but on when my contacts send messages. (Yes, you could use this to narrow down someone's time zone but not much more than that. Plus there are a million other ways to determine the time zone.)

- codethief 3y agoI don't still understand what risk push notifications represent here. Google & Apple maintain a list of all your apps, anyway. Any government can easily subpoena that list without having to put in much effort or analyze push notifications.
