@Tbayer : Data has been backfilled from bug correction date (2016-05-03 for a full day). It looks correct in Vital signs, but I'd rather have you validating that; and if you don't mind, add a new annotation about bug correction. I'll close the task after you validate the data.
Thanks !

Great, thanks! Will take a closer look, but at least the percentage of app views among overall pageviews is back to previous levels (1.3% for the week until May 22).

What about wmf.mobile_apps_uniques_daily (cf. the original bug report: T132965) and wmf.mobile_apps_uniques_monthly?

@Tbayer : I Forgot about those two (they don't depend on pageview).
Currently backfilling daily, no need to do it for monthly.

@ TBayer: Mobile apps uniques backfilled !
