Personally, if you do, I'd allow remote connection to the person(s) you trust and can talk you through the changes that will address your problem/concern. And I think it is fair to pay them for the engagement time as the problem is addressed. See Google/Apple Pay. That may not mean you will be happy with the solution, but time is time...

with their 'remote' assistance. Nothing wrong with that. We briefly touched on the matter and I'll review it further. I thought inquiring here could be useful.
