In my opinion it was a bad change the time for the challenges, the 50 battles is too much, I think it would be better with 20 or 15 battles and in addition to that every hour is changed
Yesterday I spent 2 hours farming the challenges so that they come out new and they still do not come out, I do not know if it got or what happens but they still do not change and I have already passed the 50 challenges
The dev can also add additional way to refresh the "specific" challenge such as do that challenge for 50 times, and the specific challenge will change when you want to do it for the 51 times. So you won't get bored doing the same challenge for eternity.
totally agree x2. the best items and funtions are on the challenges, 50 battles to refresh that its too much, i have a perfect digimon and i cannot boost my other digimons cause the slow and broig change, i hope than the creator turn back the change again
