You do not want to tap "New Leader" on each device - they would both then be waiting for a connection from another device. You have to make one the leader, then connect to that leader from the other device. What type of devices are you using? If you cannot connect over WiFi, that means something is blocking the TCP connection between the devices. To rule out the router being the problem, try making your phone a WiFi hotspot and connect both tablets to that. If they can then connect without issue, the problem is your router. If it's a mesh router, disable the mesh functionality.
