I had this issue with my 6s before I upgraded to my 7 Plus and it's still there. When I download a keyboard from the App Store any keyboard because I've tried just about everyone I can fine, the little voice to text microphone key isn't there unless I return to the Apple native keyboard. Is this something that I did wrong or that I messed up or how do I get it back?? Because it would be really nice to have some cute fancy keyboard while still being able to use my voice dictation I hate not being able to do both. Has anyone else had this issue?
