Adding Tuya integration

Think I had this working before, but crap happens, have been away and trying to configure the integration again, but for the life of me…
Can connect to TuyaIOT project fine and see my devices - can connect to the Tuya app on my phone (android), and all is good, can integrate Tuya, and it says it is successful, but, no devices ever show up…
Very little information in the Tuya ‘card’, just says “Depends on Cloud”, and other standard stuff (Documentation/Known issues/System Options/Disable/Delete etc). Initially had an error re: IP address denied, but added to whitelist, and all was then good…
Where have I gone wrong…?

Anyone?
As I said, all seemed to configure ok, but cannot see ANY Tuya devices (lights/switches/powerboards/climate etc).
Would REALLY appreciate being pointed in the right direction for a fix…
Thanks.
