The latest versions of both Android Build 2.7.50318 (prod 2020-05-18) and iOS Build 6.6.1 (prod 2020-06-05) mobile apps are using mobile-html to serve content and it appears that the backend has not been adjusted to register pageview counts accordingly. We need to modify the pageview definition to catch the mobile-html views.
We are seeing a significant drop in pageviews filtered by 'mobile app' when querying the /metrics endpoint of the REST API and through Pageviews Analysis on Toolforge. Our Pageviews Superset shows the drop ~ 2020-05-18 when filtered by 'mobile app' as well.
Want to be sure our analytics are setup correctly and that Analytics Engineering is aware of the change. The definition will be updated on the apps, but the webrequests from 2020-05-18 will need to be re-tagged.
@mpopov: so the good news is that webrequests (the source data from which pageview counts we use everywhere are derived) is retained for 90 days, so we can still work with AE to modify the pageview definition (since we can't modify the logged requests) and re-count the pageviews using the updated definition so it catches those mobile-html requests. the bad news is this is extra stress on an already underresourced team, so we'll have to be very nice and understanding
Other helpful information:
@JoeWalsh: Is the existing PageView counting based on requests to /page/mobile-sections-lead/ for Android and the MobileView API for iOS?
@mpopov : app pageviews are counted by looking at webrequests to the API, see PageviewDefinition.java#L111-L175 and it's looking for /page/mobile-sections/ in the absence of pageview=1 in the X-Analytics header. So as long as the apps' UserAgent validates and the apps set pageview=1 in the mobile-html requests (which are made to the MW API, right?) then the app pageview definition does not need to be modified, although it would be a good idea to make a note of the new endpoint
@JoeWalsh: It looks like we don’t set pageview=1 in either app, so it was probably caught by checking for restAppPageURIPath or iosAppPageURIQuery so there’s now an additional restAppPageURIPath that is /page/mobile-html and it’s used by both iOS and Android (previously only Android used /page/mobile-sections )
