The idle time is way to o short

The time at the end of match to go through all the info on those screens and tabs is exceedingly small, I agree (if that's what you're referring to).

I agree with both of you. You can't go AFK in a match for long enough to grab a drink or go to the restroom, and the end of match screen is also quite short and sometimes I don't have time to check my challenges progress. The button to let you move on to the next match is already implemented, no reason why they couldn't extend the timer a bit.
