Official Tuya app keeps breaking

Though you don’t mention it, I assume you use the official Tuya app for Homey. Suggest you contact the developer of the app via the contact details included on the app store page of the Tuya app.

There is also a dedicated topic on this forum for that app, where you’ll find similar reports by other users and also the same contact details of the developers: [APP] Tuya - Smart Life. Smart Living.
