Symptom

The button for switching the default language is not displayed anymore. How can I change the default language?

Cause

The default language can only be changed before you start translating a page. Once you have translated a page, the Default Language button will not be displayed anymore.

This is because, as the translated languages are saved in macros, it would be necessary to go through each page and rewrite these macros if the default language were changed. This process would be error-prone, and might also lead to conflicts with finished and unfinished translations.

Resolution

There is no resolution for this issue, as this is the expected behavior of Scroll Translations.
