This is a fix for the flashing screen issue (Flashity Flash Flash as some of the employees have named it) in Authority.
Step One: Open the registry editing tool (Regedit) as an administrator on the effected PC
Step Two: Once you have opened Regedit find the following path
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome
Step Three: Once at that location click on the Google Chrome Tab so it becomes highlighted in blue
Step Four: Right click and select New > Key
Step Five: Name the new Key the following:
LegacySameSiteCookieBehaviorEnabledForDomainList
Step Six: Inside the new key right click and create a new String Value
Step Seven: Set the name of the new String Value as 1 and the Value Data as *
Step Eight: That completes all the Regedit's. Simply restart the chrome browser and reopen Authority.
