When you click on the Adobe item on the site all you get is a blank page.
Site does not seem to have a built in reader.
In the top left corner if the window you should see a small button with a white down arrow on a blue background. Pic 1.
Click on that and a window opens offering you the choice of Opening or Saving the file. Pic 2.
Gobaith sy'n helpu. Cheers, Doug 😎
