Missing translations should default to English already:

sia-lite-wallet-web/src/translation/index.js

Lines 47 to 57 in 4eb150f

	if (!group) {
	if (language !== 'en') {
	const args = Array.from(arguments);
	args[1] = 'en';
	return translate.apply(this, args);
	}
	throw new Error(`unknown translation for ${id.join(', ')}`);
	}

yep but changing language triggers an immediate re-render. it seems that some components render before their data is loaded, so we got undefined parameters (where my guard seems to handle it, but it's a hack)
But imo yes, using i18n will be the real solution here, and more maintenable than the custom translation
