The issue is the way Apple Fixed the API was to stop those that were stealing data. That was not Signal. Apple broke something else stopping the other bad players. The API was the only way to see encrypted messages being sent without opening apps. It's also the only way I can see a Signal message on my apple watch. Now developers have to code around it because there isn't a PushAPI that should be there.
This change makes all encrypted messengers unable to show messages on Apple Watch. That wasn't stealing data this problem is collateral damage. Everyone crying about its misuse of an API. It just means Apple crippled apps. The only fix is to now have all apps just say "new message" open app to view. That's stupid.
