There is unfortunately not much we can do on our side for such problems.
Apart of course accepting the PO files directly on our tracker through merge requests — as a temporary workaround only, to avoid missing the release deadline because of platform technical problems — but for this, please get the acceptance from your language team’s coordinator (maybe it’s yourself). And maybe DL administrators too? We know we are asked not to accept PO merge requests directly usually.
In any cases, make the bug report first if the problem persists, because if it’s never reported upstream, for sure it won’t ever be fixed!
