Just letting you know, the team has confirmed that this is an error within the game - while they are working on the issue, they are recommending for checking your phone's memory and RAM space, and reinstalling the app.

Checking your memory and RAM is important, I see many of my friends with loading problems, found that they did NOT closing apps properly, so those apps will remain running in background. Not only drastically draining your battery but also makes Cookie Run progressing slowly.
