我们于开发Telegram Bot 的过程中，意外使得主帐户被停用🥲
UPDATE (June 13, 2022)
The old Telegram account is unbanned. But we are still logged out because we no longer have access to the phone number associated with the Telegram account we registered in 2018.🥲
Lesson learned: always make sure your Telegram account's phone number is up to date.
A bigger lesson may be that it's always risky to rely on a centralized third-party app to act as a Customer relationship management (CRM) system - all those chat logs are de facto client contacts, contract terms, and receipts and invoices. We are looking for alternatives. Does Signal live up to its hype?
