The app does not configure this by itself.
This is almost for sure due to a flow made by you, which listens to RAW events, and sends every incoming event as push notification, or timeline notifications (and then auto forward as push notifications. But in that case all timeline notifications should get forwarded as push notifications)
With Flow Checker app, you can find out which flows are Tuya flows, by disabling the app.
It’ll show all Tuya related flows as “broken flows”.
Now you’d find the culprit quite easy.
