Are you sure you are using the Tuya Cloud app and not this one: Tuya | Homey which is discussed here: [APP] Tuya - Connect any Tuya device with Homey (by Tuya Inc. / Athom) - Apps - Homey Community Forum
As I saw your message yesterday I went to check my Tuya Cloud app and the behavior you mention is what I witnessed too… with the official Tuya app, not the Tuya Cloud app. And the solution was exactly the same.
