Microphone input missing from Google keyboard

[AC Question]

I no longer have the option to use voice as an input method. I could be mistaken but I think this started after the recent Google Messenger update. Any idea how to get voice input option back? I'm hoping this isn't due to me taking part in the beta programs. Here's my phone info:
Nexus 6P
Google App (beta) 6.8.20.21.arm64
Nougat 7.1.1 kernal 3.20.73-ge98af56
