Starting a new message, adding the recipient now brings up addressing options for every group message that person has EVER been part of from my phone. Example I type Ringo S and if I've ever texted Ringo & Paul & George & John together or in some subset those will all come up before just Ringo's name by itself is listed. Major pain in the ass. Worse yet, even combinations including people I haven't texted in over a year - looking at you Yoko - are listed, often before the one person I really want to text. Never happened before iOS 11. HELP!
