Hello,
The WMF's iOS App team is glad to announce that version 5.0.2 of our app has been released to the App Store[1]. This is an expedited bug fix to address issues with links into the app. These issues were caused by the iOS 9.3 release and have hit many apps, causing links to fail or apps to stall on startup[2]. Working with Apple we have incorporated their fix and the issue appears to be resolved for our app (you may still see this with other apps until iOS 9.3.1 is released).
In addition to more stable link handling we have a couple other small improvements included: - Fixed an issue where some "Read More" recommendations were hidden or missing from article footers. - Additional localizations from TranslateWiki.
Thanks, Josh Minor
