How to make gettext working in umbrella app?

Hello everybody,

I just discovered (example article) how gettext is easy to use thanks to the mix gettext.extract task…
But I also noticed that it’s not working (nothing is generated) when in an umbrella app.
I tried both from the umbrella root and from the phoenix app_web root.

It seems to be something known (example post from this forum) but when I look into the mentioned github issues, I don’t really get how to make it working.

Is there some kind of update that can make it working out of the box?
If not, what could I do?

Thank you (and sorry if it’s obvious, I should’ve missed it…)

I was tried in the past and notice that with umbrella don’t work’s…
I would like to know as well!!!
