Dragino shield v1.4 TTN stack anomalies

Dear all,

I create my LoRa node with Dragino gateway LPS8 and two project with arduino MKR1310 e Dragino shield v1.4 over the arduino mega 2560.
MKRwan working perfectly instead with Dragino shield I have no feedback on the application end device activity, despite LPS8 gateway receive the uplink message. With the previous network v2, that issue did not happen, I guess it is depending on the end device configuration but I tried different options for the network layer but nothing change max I receive one message after several hours, there has been someone who has had these problems?
