***Update, 8/11/17 - I like and rely heavily on this app but am constantly hitting two button that I deem unnecessary and truly annoying - the telephone button and the "invite to Messenger" button. First - I dont know of anyone who uses this in lieu of their phone, I cant believe that this is a common use for the app that the phone needs to always be on screen. Second - I still dont know how I keep inadvertently "inviting" people to use Messenger when Im already in a message conversation with them - that pop up is infuriating. Please disable when users are already in a chat with a particular person.*** First, I see no reason why this is a separate app from the Facebook app - you can access it from Facebook, still see a notification and open a message from Facebook, and Im not noticing any significant improvements over the original. Meanwhile, that stupid black "turn on your notifications" screen that pops up every single time the app is opened, regardless of whether you have on all notifications, none of them, or some, is completely unnecessary and absolutely infuriating. Seriously, Messenger, what the heck?!? We all know about setting notifications and that screen is helpful the first time but at a minimum, there should be a "dont show me this again" button. No pun intended, but we got the message. We either took our advice in some measure or chose not to. Now just stop. Ruins my enjoyment of opening the app to go see a message and getting interrupted by that stupid screen popping up.
