Chrome Version 77 introduced a change that removes the option to "Always" open file types from external applications in their browser. If the user had checked this option prior to being updated to version 77, the same behavior will continue. However, if the user had not checked this option prior to being updated to version 77, there is no way to get this option restored. As a result, each time the user engages the Viewer from ResponseFull, they will be prompted to allow the external file to open.
Resolution: Chrome 84 remembers user preferences when launching external protocols.
As requested by IT admins, Chrome version 84 (released July 14th), gives users back the option to select "Always allow for this site " when opening an external protocol like the ResponseFull Viewer. When you upgrade to Chrome 84, you can now check this box and it will remember the option so that you do not have to "allow" each time you engage the Viewer.
