Apple’s iCloud website is currently experiencing some issues that will prevent some users from accessing key features. That includes the Web version of iCloud Calendar and Reminders.
Both Web apps won’t currently load, leaving users without any access to their calendar through a Website. “There was a problem loading the application,” the error reads, without providing any additional details. Apple’s support systems status website doesn’t indicate any major issues with those properties, however, and suggests both are operating properly. It’s unclear how long they’ll be offline, or why, but Apple usually gets things up and running.
Just a quick warning for you, in case you’re wondering if you’re the only one locked out: you’re not.
