Hi Bjørn,
let me explain how the multi-lang works in the app (the one in Moodle core, I guess the V2 will be the same but this is a 3rd party plugin so I might be wrong).
Most of the content retrieved by the app is filtered at
server side, before the app receives the content. That means the app will only receive the text in the "final" language, not all the languages. By default this filtering will use the language selected by the user in LMS (the selector you sent), but the Moodle app sends Moodle a parameter to indicate which language to use instead of the one selected by the user. The language sent by the app is the one selected in App settings.
Please notice that the Moodle app has a cache system to decrease the network usage. The Moodle app stores most of the content received from LMS and it won't request it again in a while. This means that the following can happen:
- A user has the app configured in English.
- The user opens a course in the app and sees a certain multi-lang content in English.
- The user goes to App settings and changes the language to German.
- The user opens the same content again. The app displays the content already stored in the app, so the multi-lang is still displayed in English. If the user performs a "Pull to refresh", the app will re-fetch the data from the server and now the content should be in German.
Can you please check if this is your case and it works fine after performing a Pull to refresh?
If it still doesn't work, can you please tell me your Moodle version and where do you have those multi-lang texts? E.g. a section description, a book, etc.
Cheers,
Dani
