There is discussion about tranditional Chinese(zh_hant) and simpfied Chinese(zh_hans). [https://stackoverflow.com/questions/4892372/language-codes-for-simplified-chinese-and-traditional-chinese](url) Hong Kong, Macau and Taiwan use tranditional Chinese.

I have the same "Could not reach Cloud Firestore backend. Backend didn't respond within 10 seconds." problem. solved by downgrade to firebase-js-sdk to 10.6.0

`const db = initializeFirestore(app, { useFetchStreams: false })` 10.8.0 Successed

hope there is v9 support soon. I spend 1 day convert my code to v9 but stuck in firebaseui

one-time for a small money is OK.
