I had been told by Ancestry when I phoned that what I wanted to do was impossible as the search always picked up my ISP address and chose the most appropriate
However persevering with Tom's suggestion, I think I might have got it to work
- thank you.
I went into the Search all Records as if I was starting a completely new person search and then clicked on Show Advanced. I then chose All Collections and checked the box. When I went back to searching for records from within the profile of someone already in my tree this now showed all collections
and seems to stay like that now as the default.
All I need now is for the site to be working properly
