Resource cancel.voc for lang pt-br not found

I’ve tried to install wiktionary and play spotify from the skills marketplace, but keep getting a skill error. I’m using it on Arch, with pt-br lang, . Tried to answer yes, but since it only recognizes portuguese I guess it won’t work anyway.

This is what appears in the cli client:

there are only pt-pt ressources (in that regard)
(yet it should fall back to en-us if ressources aren’t there)
