Apple's latest update to the iPhone and iPad is, apparently, not so great.
Users are complaining about a bug that causes apps and devices to freeze and crash.
After apple released iOS 9.3 last week, many people who updated their phones and tablets reported problems with opening links in Safari, Chrome, Mail and other apps.
In some cases, older iPhones and iPads completely froze.
Apple has yet to acknowledge the issue, but customers in support forums say the company is aware of the problem and working on an update.
Apple's new Apple Support Twitter account has also been flooded with reports of the bug.
