We are improving the Sequoia theme with every update with new features and options. Some of them are displayed on the front-end of the website. Therefore, it needs to update the language and translation files to translate the new strings in the theme.
The first thing to do is to update the main language file, where all the theme strings are stored. Go to the Dashboard > Loco Translate > Themes > Sequoia and choose Edit template.
This is NOT a translation file. Manual editing of source strings is not recommended.
Click on the Sync button to merge new strings from the source code into the main language file.
Click on the Save button to save the new strings. Go to the list of translation files for updating the needed translations. Select your translation file and click on the Sync button and Save changes.
