Problem / bug feedback .... I too have the same bug. I have a Samsung Galaxy S6 (single sim) and can't find option in the settings (general or advanced) to disable the 'dual sim' support and get rid of the little numbers on the envelopes :/
Yikes!!! Hate the update!!! I want to go back please!!! Your idea of a great update is horrible. I don't need 2 options of sending. And regardless the buttons are so small they both get pressed at the same time anyway. I want the little envelope back so I know it went through. I get pop ups now asking if I really want to send it. 6 times!!! If my reception is bad it continues to send and list 5-6 tries repeatedly so my inbox is filled with those. When it does go it sends triple texts. PUT IT BACK PLEASE!!! IT WAS GOOD BEFORE!
Dual Sim Issue I have a Moto X with a single Sim card but can't get rid of the dual Sim options. The two send buttons and numbers by my texts are really aggravating me.
Last update created an issue... App locks on add for the New GIF expression library. Can't get into the app at all. Pop up texts still come in, but no way to view other texts... Outside of this issue, I love the app.
New update I don't need the dual SIM. I don't like the little icons that show up on my messages with numbers. I don't see the option where i can remove it under general settings.
