Nothing infuriates me more than the fact that when you get a missed call, tapping on the call notification doesn't call them back, instead it takes you to their contact!!!
What's worse is that this is a regression, so they actively made life a little more difficult for everyone in the new release.
Personally, I prefer that. I don't want to talk to people, usually. I want to go to the contact, see what communication forms we have in common, and send them a message.
I bet that they A/B tested this on users and this is not just a random change.
Perhaps this should be an option but I far prefer that tapping on a notification not do something that potentially notifies the sender that I saw the notification, certainly not calling them. I want to initiate that action knowingly and intentionally.
