@Pginer-WMF, @ngkountas, when the messages of the invitation panel will be available on translatewiki for internationalization? Thanks.

The code for this is still in review. On the right column there is a "tags" section that shows the status of the ticket for the current work board "Language-Team (Language-2021-January-March)". Once the code is merged, you'll see that gerritbot adds a comment in the style of "Change XYZ merged by jenkins-bot...". Code needs to be merged and exported before it is available for translation.

Given that it is possible that, even after merging, some additional changes may be needed, I think the best time to look into translations is when the ticket is marked as resolved since all the checks will be completed by then.

@Pginer-WMF, I just saw that the confirm panel is now in SX test server, see screenshots:

The change is now ready, @Pginer-WMF

the translated article and the missing article are the same.
this way we can never see the "Expand another article" message.

@ngkountas fix on this ticket or new one?

Nik can confirm, but I think the problem here is that the API to check for sections is looking at the real articles and the section is added to the test instance one. If this is the case, this would be one of the aspects to verify on a real wiki.

Having said that, when publishing to the sandbox we may find a similar issue even on a real wiki. So it may be worth processing the list of missing sections in a way that we surface in the example the next one to the one added.

Pau described the issue accurately. In general API to check for sections has currently serious limitations in finding missing and present sections.
