Perhaps it would help if people mentioned what platform they are running, e.g.:
Windows 10, Firefox 63. Tick box. (from the beginning)
Windows 10, Edge Picture grid. (first attempt)
Windows 10, Internet Explorer. Picture grid.
(first attempt. Then failed with "Can't reach this page" msg)
The pictures take sveral attempts - very frustrating.
All run from the same machine, but I did have to log in separately for each browser.
