Link expired. This invitation link has expired

When you hit button in cart or floating widget you received a warning with message: “Link expired. This invitation link has expired” and chat never starts.

In Edit Account you see “Account username or Channel name” label but below the field a warning says “Please enter a valid phone number or group link” hen you tried to fill in an account username. The field only let to fill a telephone number with format like +19876543210 but after many tests, chat never works.

This plugin looks awesome, and promising, but I assume it is outdated, because Telegram made some major changes in the last months.
