Why Isn’t the Dota 2 Battle Pass (Battle Pass 2021) Working?

Many people encountered an issue on August 17, 2021, starting from 21:00 Moscow time when the Battle Pass for the year 2021 stopped working. Players began to search online for answers because the Compendium was still there, but they couldn’t select anything or access the tasks. The answer is quite simple: the Battle Pass ended as of today. The developers just haven’t removed the game files yet, so many still have their tasks and other items, but nothing can be selected because it’s no longer valid.
