So I LOVE the Textra app, but after I just upgraded to Nougat on my OnePlus 3T - I noticed that my text message notifications disappear from the notification tray on my main screen after a while. It used to be that they would stay in the notification bar until I accessed/dismissed them and then they'd disappear.
Now I get a message and it temporarily shows the Textra notification icon in the tray at the top of the main screen, but if I lock the phone without answering and then unlock it again the notification disappears.
This is inconvenient because after a few hours away from my phone, I have no indication that I got any texts unless I remember to open up the Textra app and see what's new. I liked it better before.
I couldn't figure out where to ask Textra directly - so I came here.
