I will definitely pursue that angle with her.
I find myself suddenly incompetent at posting replies and I have fragmented my replies badly.
there are 6 parts to what I am saying, so please read on.
In the end, after finding a dumb mistake when I failed to follow the engineers instruction, I did get dictation working (at least for now) on my iPhone 5s with ios12 by making changes in the setup parameters for the keyboard support.
I consider that a bypass rather than a solution for me, but maybe it really is a solution for the IOS13 version of dictation support.
I don't know, but maybe there are similar settings for the dictation and keyboard support on desktop.
In any case I will ask Crystal for the best way to proceed with what you need.
She will know if a new case has to be opened with desktop support, and if so, she will probably want you to be the customer for that case. After all, I have zero background with using Apple desktop at all. When I can, I'll get some answers back to get you plugged in.
I don't think we want to do much more right away. i.e. during our thanksgiving dinner preparation and feasting.
I'll reply back to you again as soon my circumstances allow me to.
