Missing option for dictation in messages on Apple Watch Series 11

Thanks!

When I switched to English US the microphone did reappear, however when I switched back to English Canada the microphone button was gone. However if I swipe up on the watch keyboard I can choose between the two, and only the English US keyboard offers the microphone button.

Same here. For each message thread I’ve had to switch keyboard language (sometimes twice) and actually send a message for the change to register. If I just change the language and select the microphone and then cancel without sending a message, I won’t see the microphone option (only keyboard and finger options) next time, unless I go through the whole language process again.

I fixed it by ensuring that I had English (Canada) only in my phone keyboard settings and the microphone came back.
