This is my signup page code where the user is successfully written to Firebase Authentication, but Firestore does not store the user data. The process seems to stall after the authentication step, with no errors shown in the console or feedback on why Firestore isn’t being updated. I’ve confirmed that the user is created in Firebase Auth, and I’ve attempted to troubleshoot by checking Firestore rules and ensuring they allow write access. Additionally, I’ve tried adding print statements to confirm the flow of the code reaches the Firestore write operation, but it seems like the operation either doesn’t execute or fails silently. I’m seeking advice on potential reasons for this issue and how to debug it, as I’m currently stuck without any error messages to guide the troubleshooting process.

I fixed the issue; it was due to a VPN setting that I had set up a long time ago
Sometimes, when you’re working with Firestore, you might encounter security issues that prevent you from writing data to the database. These issues are known as Firebase security rules. They’re like the guardians of your data, making sure that only authorized users can access and modify it.
And please look at the picture below to set the rules in Firestore.
