## **Description**
After trying to add a block explorer the Add Custom Network modal
pops-up. I am adding block explorer by using device keypad enter button
because the Add Block Explorer URL button is not reachable, keypad in
the way. May be because of the keypad that is causing this.

Have not been able to successfully add a block explorer.
