Tabs device never seen after re-registration


I successfully registered a Tabs (temp/humidity) to an application. My gateway was receiving the uplinks and the data was received by my application. I later decided to move this particular device to a new application, so I removed it from the original and then went through the device registration process thinking this would be a straight forward process… but the device is ‘never seen’. Obviously I’ve checked that I have the correct JoinEUI, DevEUI and AppKey but still no data. I can see the uplinks (but no join requests) in my gateway traffic but it’s not received by my application. I must be overlooking something. Does anyone have any ideas? Many thanks for your help
