Telegram-TT Language Change Guide

I’m customising the open-source project at https://github.com/Ajaxy/telegram-tt and need clear, step-by-step instructions for making the interface stay in Traditional Chinese instead of snapping back to English once the React app finishes loading.

Here’s what I’ve tried so far:
• Edited /src/assets/localization/initialStrings.ts
• Tweaked fallback.strings

Those edits show the correct language only during the initial render; as soon as the React state hydrates, English takes over.


• Where the definitive locale is set in telegram-tt
• How to add or replace strings so Traditional Chinese persists after hydration
