Genesys Cloud - Main

Hello folks

Our staff who make a number of outbound calls who like to select the "Prepopulate queue field with last used queue" preference to speed things up on outbound calls. Lately, despite checking the box and making successful outbound calls, when agents come in on their next shift (or close the browser and reopen), the queue field is blank and the check box is empty. I have tested this on-site and it fails....  but off-site the feature works as expected. 

We have a pretty aggressive cache-clearing GPO on closing of the browser, but my understanding is the saved preference is meant to be on the server side – persisting "[…] after refresh, login or logout, and across browsers and devices." (Enable last-used queue for outbound interactions on behalf of a queue - Genesys Cloud Resource Center) so I don't understand how any cache-clearing or GPOs could affect this. 

If anyone has some insights that we could check, it would be greatly appreciated. thanks muchly.
