It looks like Apple has broken Safari with the recent iOS 9.3 release, as many iPhone and iPad owners are reporting that they are unable to open links in the browser from within other applications. In other cases, opening links in Safari is causing the browser to either freeze or just straight up crash.
I have also been facing this issue on my iPad Air 2 after updating it to iOS 9.3, though the issue has not cropped up for the last couple of days now.
This is not the first time that Apple has broken Safari with an iOS update. The company has in the past broken Safari with iOS updates, which it then fixed a few days later by releasing a minor point release. Thus, it is likely that Apple will release an iOS 9.3.1 update later this week or sometime in the first week of April to fix this issue.
Until then, you can try switching to Chrome or any other browser of your choice for all your browsing needs on your iPhone or iPad.
The iOS 9.3 rollout has been quite troublesome for Apple, with older iPads facing activation issue after installing the update.
Are you facing any issues with Safari on your iPhone or iPad after updating to iOS 9.3?
