Twice this has happened. I've gone into a number via my call log and clicked to block it, it then gives you slide bar options to block either calls and / or texts - I always slide it to both. And both times I have received text messages from the numbers after supposedly blocking them. When I go through my message settings, the numbers are on the block list, so why am I still getting texts? Does it have something to do with the Messenger App (originally from Facebook Messenger) and the SMS Messenger having to merge into one App to be used as one?
