Investigate deep link behavior changes in iOS 10.3 and/or Wikipedia 5.4.1 and on
Closed, ResolvedPublic1 Estimated Story Points


We've seen a dip in retention, both in internal (see parent ticket) and Apple numbers and also overall monthly active user count. These changes don't coincide with any meaningful feature or design changes, but do occur around the release of 5.4.1 and iOS 10.3.0.

We noted a change in deeplink behavior and fixed an issue we had caused back then, but its also possible iOS changed in some way that the app is no longer perferred, resulting in a drop in retention. There may have been a drop in pageviews as well, masked by an unrelated issue (see parent).
