The help on this site says that the problem only exists when SwiftKey or Swype keyboards are installed and one button nav is on, works fine with gboard. That's false though. I use gboard and have to disable one button nav for textra to be able to function as it should and show the attachment menu at the bottom. It appears this problem in textra is related to one button nav, not the keyboard used.
