Why did the Mi cloud input fail to paste?

Why did the Mi cloud input fail to paste?
First, check whether the Mi account logged in from the computer and the phone are the same account.
If the same account fails to paste, you can also try to select cloud input from the clipboard by clicking the "https://cdn.cnbj1.fds.api.mi-img.com/micloud41/789/9-2.png" icon in the lower right of the input box.
Secondly, the following reasons will also cause the paste failure:
• Cloud input paste failure may be the cause of the network, you can refresh the network and try again.
• Your current version does not support cloud input, which also causes a paste failure.If there are no network problems, please try to upgrade the version and try again.
