In Safari, Apple has a default setting (Prevent Cross-Site Tracking) that prevents advertisers from putting a cookie on your browser, called Intelligent Tracking Prevention.
Adobe looks for a cookie put on the computer by Liscio, which delivers the fillable document (eDoc). With "Prevent Cross-Site Tracking" turned on, Safari blocks the eDoc from appearing. This effects all Adobe products. If an eDoc cannot be accessed in Liscio while using the Safari browser, the "Prevent Cross-Site Tracking" setting must be turned off.
Here's how:
Open Safari
Select Safari at the top of your computer screen
Select Preferences in the menu bar
Uncheck Prevent cross-site tracking
Refresh your Liscio page - you should now have access to the eDoc
If you prefer not to turn off the setting, a different browser can be used to access eDocs.
