Idle Online Universe RPG

I have just returned to the game after a long-ish break and have noticed my challenge progress has been reset, im level 256 but cant get to higher challenges since i need to beat bronze in duo, i could easily do it myself but im forced to wait for another. is there any way around this?

You can't start them alone. All you can do it ask for a filler in kong or guild chat, duos shouldn't take long but groups can be a nightmare.
