I have an LG G6 and on the texting app, it's showing new conversations being pinned automatically without me doing that. I don't want those conversations showing up on top of my other conversations. I only have an option to pin them, but not unpin them. What can I do for a workaround? Long holding a pinned conversation only gives me an option to delete them. The three-dotted top-right drop down menu has no option either.
