I want to download TRTH API Best Practice v12.1 here: https://developers./sites/default/files/Tick_Hist_User_Guide_July2018.pdf, but I get "site cannot be reached". Is this document available?. The TR Dev Portal site references the doc here: https://developers.refinitiv.com/en/api-catalog/refinitiv-tick-history/refinitiv-tick-history-rth-rest-api/documentation#tick-history-gui-user-guide.
