Content Language Issue (Piefed)

I just found the "Content Language" in Piefed Preferences (on desktop) and enabled it, after removing the foreign language instances I had blocked previously. The preferences appears to be 99% working on desktop browser (chromium), but not working on mobile via voyager.

Is Piefed's "Content Language" an enabled feature on Voyager? If so, how can I enable it on Voyager, if it's already enabled on my piefed account?
