OK, I'll bite..
I'm not expecting anything - I never do.
Which "you" didn't on this occasion hence me raising my confusion here...
Nope, all it says is that that an email conversation has been started - with no actual conversation in it.
Ah, there's the bit that explains things...and if it had been sent in a follow-up email then all confusion would have been cleared up.
Now, if you are referring to this in my reply as causing your own confusion:
I posted my comment twice previously, via the PWA - it appeared briefly, then disappeared. I then posted it a third via a browser, with the added note, and it remained. Hence my comment.
