Spent a little time with our EV salesman
Problem 3 can be purchased at any RV store.
Problem 3. If we read your post correctly your phone works just fine but you cant get other phone connect so I assume you used the code on the charger to register these other phones to the charger. If that has been done then you need to find out why they are disconnecting, weak signal or some other reason.
I’ll try and get more information with problem one
