What is the notification number and word count supported by the Xiaomi Smart Band 8?

Messages in the notification list keep up to the latest 20 messages. Tap to clear all messages in the current list. Support read-after-read function (read messages on the phone and delete them automatically on the band).
Messages can be viewed by turning pages. The maximum number of words displayed on the bracelet is 400, which is usually the same as the number of words displayed on the notification bar of the cell phone. Also, it is related to the specific APP.
It doesn't support image message display, but supports some common emoji (version 1.1.122 or above). The unsupported emoji will be displayed as "□" on the band.
Note:
The emoji display on the band is related to the specific emoji. The emoji that comes with the input method is more adaptable than the emoji in the APP.
