I have the monthly subscription and noticed that my guides are missing after 1-12 leveling is done. I made sure I am logged into my account and even says my username and not as a trial user. I also made sure the file path to the classic addons folder is correct. See below:
Hi the WoW Classic Guides are seperate one off purchase and not part of the subscription. You need to purchase the guide and reinstall, you don’t need the sub for the Classic guide
