I recently started playing the campaigns and was enjoying myself, but today all the campaigns have become locked.
Some of them redirected me to the DLC page, which I could understand, but others gave me an error message.
Yesterday, I was on the final mission of the Joan of Arc campaign, but today I couldn’t access the save because it said I didn’t have access to the DLC.
It seems that most of the civilizations are also locked in Skirmish mode.
I’m not sure if this is a glitch or if everything is now behind a paywall.
I may need to uninstall and reinstall the game, and I’ll update my post in case others are experiencing the same issue.
However, I discovered that if I repeatedly selected the campaign, it would take me to the store page to buy the DLC but then give me an error and bring me back to the game menu.
After doing this a few times, the campaign became unlocked, and I was able to play normally.
