It took longer than us users, we would like. But here's the thing: Apple just released the iOS 9.3.1 (compilation 13E238) to fix the link problem in Safari, Mail, Notes, WhatsApp and many other apps.
The update is available both from the device itself (General Software Update Settings) and iTunes (just plug the device into the computer and open iTunes for a warning about the update to appear).
The link bug seemed to be related to the Booking app and the universal links feature. Do you know when you open a Booking link and, instead of opening it in the browser, you are taken into the app? This feature universal links. The problem that Booking's base of associated sites (which leads to a given link to open within the app) was huge, which caused an overload on the resource that failed to analyze the content of the link and, consequently, caused the bug.
This problem, however, was not peculiar to Booking; other apps like Wikipedia Mobile, just to mention one more also had the bug in the archive of associated sites.
Both ran to correct this defect but, even excluding the apps and reinstalling them, users continued to struggle due to cache of iOS itself. They even painted by alternative means of forcing a cleaning of cache iOS; However, we tested everything and nothing solved the problem.
