messaging using voice on apple watch

Apple Watch Dictation/Scribble...

I was the same as all of you.  With the new update I lost the voice dictation and scribble pad options on my Apple Watch screen options.  I checked to make sure my dictation in my phones settings was "enabled"...and it was.  I turned it off and turned it back on...nothing.  I turned it off, rebooted my phone and watch them turned out back on and rebooted again...nothing.  I few days ago I was messing with my watch imessages again.  I was in my daughters text to me, I tapped in the iMessage or SMS (if not an Apple device) to see if by some chance the voice dictation mic icons and scribble pad came back...they didn't.  In my frustration I swipped up on the screen...and to my surprise it swipped up to a bar with a "blue hand pic and the word scribble".  I tapped on it and "both" the scribble pad and dictation mic icon options were there.  As I investigated this more...I have learned that it only opens up the "dictation and scribble" options to that one (1) texts you are in...but it stays there after that.  So when you go on someone elses text to reply to them...you have to do that "iMessage swipe up, tap on scribble bar" to get the "scribble pad and dictation icon" process again to appear like it was before the update.  I hate that we have to do this extra step...but I'm glad I found it, figured it out and have it back on my Apple Watch iMessages.  I hope this helps and works for you too.
