SOLVED!!! Wow, the samsung reps on here should NOT be getting paid. So for me, and I have no idea how it happened, i had somehow pinned several text conversations to the top. Anything else would show up below those even though they're more recent. If there's a little thumbtack next to the conversation, it's pinned.
@unsungsammy yeah the moderators weren't provided the screenshots immediately where the pinned conversations were shown. But those pinned conversations were definitely the problem. Way to go on figuring it out!
