Yes it took me about 30 minutes, but this is still a lot for something we need to do every weekend and most of this time is spent in fixing the formats (notably in links). This time could be divided by two, and it should be simpler to review the translations, by more volunteers, and (more importantly) in more languages. Most contributors, when thy comm on the week end will just spend not more than a couple of hours, and asking them to spend 30 minutes every week is still a lot.
As these notifications as meant to be short, very synthetic, in order to be delivered more largely for awareness (even if all the inner details are not translated, many people just wen to be advised, or being linked to a source of this information within larger support discussions), the time to complete these translations should be minimized as most as possible (we have lots of other things to do, including in other Wikimedia projects, or related projects, where most tech ambassadors also have work to do and need time to do it).
