This project is a fresh work, it should work, but please don't be shy and discuss it with us if any issue ♥️
TL;DR: Stop translating in "manifest.json" otherwise this work will be lost.
Packages includes a "manifest.json" file, including questions.
English strings are extracted once a day and arrives in Weblate.
One a week, it will be pushed to the Apps repository (and reach end-user through automatic download or manual refresh).
If there is translation in source package, will it be overridden? Apart from the english strings, yes.
Note: questions in manifest without english are not available in Weblate, here is the script to check: https://gist.github.com/Psycojoker/523af81077f86ba2985a135aa4a3b929
