If I have unread messages that I haven't seen and Textra gets upgraded to a new version or my phone restarts, the notifications for those messages go away and do not come back. I often miss messages for hours to days because I don't go into Textra to look to look for messages unless there are notifications that I have some unread. There are other apps (Google voice is a good example) that reinstate their "unread messages" notifications after a phone restart. I would like to see Textra do this as well.
