Facebook messenger is so annoying to use too! My extended family group chat is there, but I had to turn off notifications because Facebook realized I only engage there and started serving me stories and updates from the messenger app as notifications! Right this second opening messenger it shows a “4” in the upper right, assumably with garbage notifications about things I don’t care about “happening” on Facebook. Luckily if something important actually happens my family knows to text me, so I read the group chatter at my leisure rather than being interrupted randomly.
