Appwrite phone auth not working! Please check URGENT

My project is live and suddenly now phone authentication is not working since yesterday evening. I am getting OTP successful sent msg but user is not receiving OTP. Please check this issue ASAP. I have already raised this issue in support also. I am using APPWRITE PRO.

TL;DR

Issue reported: Developers experiencing phone authentication problems in their Appwrite projects, specifically with Indian numbers not receiving OTPs. Solution: Developers need to provide specific details (phone number used, timestamp of test) to investigate the issue further and potentially resolve it. Mentioning the project ID may also help in resolving the problem. Developers have raised the issue in support and are using Appwrite Pro for their project.
