Steps to replicate the issue (include links if applicable):

My new device is a Samsung a16 phone.
Every citation renders as a "0" when reading an article, instead of numbering in the normal way. If I click on them, the little dialogue comes up fine. I checked for an app update, I'm current.

What happens?:

See above

What should have happened instead?:

Citations should enumerate starting with 1, lol

Software version (on Special:Version page; skip for WMF-hosted wikis like Wikipedia):
