Issue with PLURAL

(Generally, it's better to ask such things at Support, but I don't mind replying here.)

This is a translation of the Android app and not of a MediaWiki component. For technical reasons, translation for Android requires that all possible plural forms are written, even if they are identical.

You probably need to write something like this: {{PLURAL|one=dec'h|two=%d devezh zo|few=%d devezh zo|many=%d devezh zo|%d devezh zo}}.

For reference, the complete plural rules for all languages including Breton appear at https://unicode-org.github.io/cldr-staging/charts/latest/supplemental/language_plural_rules.html .

Thanks.
