Roger Rosner, vice president of applications at Apple Inc., speaks during a company product launch event at the Steve Jobs Theater at Apple Park on March 25, 2019 in Cupertino, California.

Just one day after a splashy and star-studded Apple event where the company announced new services, one of them wasn't working properly. Apple News+, which costs $9.99 per month, was crashing for users Tuesday morning.

Apple has since fixed the issue and it is now functioning as designed.

Earlier Tuesday, CNBC opened the app on an iPad and tried to read several stories, but noticed the app crashed about three times in three minutes. It was slow to load content and seemed to crash while moving through the app or scrolling through content. It was more reliable on an iPhone.

Apple News+ will cost $9.99 per month after a free 30-day trial period. And any access to stories from 300 magazines, The Wall Street Journal and the Los Angeles Times is limited to reading inside Apple News. You can't, for example, log into the Journal's website to read premium content without a separate WSJ account.

That means people who were trying to read the news earlier Tuesday, or who expect to get access when they pay $9.99 per month, will need Apple News to work in order to access the content they're paying for. There's no other way.

New software is often prone to bugs, and Apple's other apps that serve millions of users, such as Apple Music, don't crash often.
