Why can't I use dictation with my airpod pro's?

I am unable to use the voice to text dictation feature with my airpod pros. Dictation works fine when not using airpods, and the microphone on the airpods works fine as well, as I am able to make phone calls. I have tried resetting/repairing the airpods, restarting my phone etc, and every other workaround on the internet I can find shot of a complete factory rest on my phone. Siri and dictation are enabled. Any ideas?
