The Android Wikipedia app (iOS untested/unreported) repeatedly shows outdated content on German Wikipedia, see [discussion](https://de.wikipedia.org/w/index.php?title=Wikipedia:Administratoren/Notizen&oldid=245469518#Wikidata-Vandalismus_bleibt_in_der_Wikipedia-App_sichtbar)
**Steps to replicate the issue** (include links if applicable):
* Browse to https://de.wikipedia.org/api/rest_v1/page/mobile-html/Adam_Wharton
**What happens?**:
* Note that the infobox shows
> Geburtstag 2. Juni 2004
**What should have happened instead?**:
* It should show the same content as the website https://de.wikipedia.org/wiki/Adam_Wharton
namely
> Geburtstag 6. Februar 2004
**Other information** (browser name/version, screenshots, etc.):
Browser does not seem to matter.
UPDATE: Works now after a purge, but purging should not be necessary.
