Have you double checked that your command (including the way AutoVoice or Auto Voice) is identical with what is shown when you give the command directly to the assistant as apposed to what you have written in the routine?
Google Assistant seems to be rather too supercilious about how it looks at verbs. I'm just going to have to get creative with how I word my commands.
Many thanks for you help, Rich. I now seem to be on my way.
That does exactly what I was looking for. If I'd known about it a day earlier I'd've saved myself the price of AutoVoice :)
