I understand the user locale and the examples are useful for English (en-US) to Spanish(es-US) translations.
What is usable at the current time? A list would be nice of what is supported by Inductive Automation.
I hate to assume that everything in this link can be translated.
This is probably the list to pay attention to: Java 11 Supported Locales
Note that “support” means pretty little - you are responsible for managing translations in your system, we just provide the mechanism to define them.
The link is exactly what I was looking for. I can provide the translation, just needed to know what locales I can use. Thank you.
