When using selective sync, you are prompted to select the products after clicking the Run Publisher Service Sync. It's not immediately obvious that in order to select more than one item at a time, you have to either use Ctrl+Click
, Shift+Click
, or Ctrl+A
(depending on your choices). I think these options should stay, but it would also be helpful to include a checkbox beside each product along with a "Check/Uncheck All" checkbox. This makes it clearer on how to make a custom selection of available manual sync products.
