Hello,
A heads up that the Reading Web team has been updating the MobileFrontend
schema code to use mw.eventLog rather than the custom Schema class [1].
This will mean that MobileFrontend won't support logging events anymore if
sendBeacon is not supported. We used to use localStorage to support
non-sendBeacon browsers.
