1. The Tapo App could benefit from a "Refresh" command added to the Device Info panel in the Tapo App. Testing the connection of the device would be much easier if this page had a Refresh feature. The signal connection information in the Tapo App often conflicts with the signal information for the same device as indicated in the Tether app. 

2. Tapo App connects quickly to the C120 camera when my iPhone is not on the local network, using cell data. The Tapo App takes a long time, up to 30 seconds or longer to connect to the camera when my iPhone is on the WiFi network with the camera. I have tried turning off the cell data while connected to the WiFi network but that action didn't fix the connection problem.
