Dapper wallet in Rinkeby not working

[nicosampler]

Not sure if this is the correct place to report this problem, but seems the most suitable of all repositories,

I'm trying to make work Dapper extension for Rinkeby, I downloaded the extension from here https://www.meetdapper.com/docs/start. After installing it, fails when I try to sing up or log in (with mainnet credentials)

Por lo visto no responden por este medio, tengo un problema como mi billetera dapper, se quedo en un bucle donde pide que autorize a un nuevo dispositivo pero no tengo ninguno.
