Account binding is successful, but the device does not appear?

Screenshot of problem:

Problem cause 1: The devices associated with the account do not support the voice platform.

Solution: Check whether the corresponding device supports it by querying its device ID for PID on the IoT platform, and confirm whether it supports the corresponding voice platform according to the PID.

Problem cause 2: The user has confused the account to which the device belongs. The user may have multiple accounts, and the device is bound to account A, but entered  account B during binding", which will result in the device not being visible.

Solution: Suggest that users confirm whether the account binding skill is correct in the app where they can see the device. Click "Me", click the top right corner settings, click "Account and Security", and confirm it here.
