Hello,
My add-on should be super fast. If loading page takes more than half a second, something is wrong.
Please contact me to my support e-mail.
Also make sure you are NOT using Cloud-dials page as your homepage - instead set it up using the proper add-on URL. Just follow the steps written in Options page / first tab / first line.

Have a nice day :)

Best regards,

Juraj Mäsiar
