**Steps to replicate the issue** (include links if applicable):
* Open Wikipedia Android Mobile App
* Go to any article containing a `<ref>` tag with a `group="xxx"` parameter so that the local Wiki has a `MediaWiki:Cite link label group-xxx` page.
**What happens?**: The footnote reference is labelled `xxx + number`. For instance, if the group is `alpha`, the footnotes are labelled `alpha 1`, `alpha 2`, etc. (cf. screenshot below).
**What should have happened instead?**: The footnote references should be as defined in the local page `MediaWiki:Cite link label group-xxx`. For instance, on French Wikipedia, the references of group `alpha` should be labelled `a`, `b`, `c`, etc. (cf. [[ https://fr.wikipedia.org/wiki/MediaWiki:Cite_link_label_group-alpha | MediaWiki:Cite link label group-alpha ]])
**Software version** (skip for WMF-hosted wikis like Wikipedia):
