Really thanks for the reply and for clarifications. That’s a very good news.
I’ll re-support the app and I’ll add a banner to advise users to report on Mozilla Discourse or GitHub bugs or problems got on website.
I hope Mozilla will understand the app is just to improve the project.
I’m a developer and I can unserstand the pressure Mozilla developers have as well, and the app should be a better news for them, because they could concentrate on desktop mainly, instead of both desktop and mobile.
