Yesterday it seemed to pick up the missions and kobans as expected but today when the missions refreshed and the timer was gone, no mission was picked up and I had to manually select it. But afterwards, it picked up the next mission right after it collects the reward. So it seems there might be a gap of coverage right when new missions become available that needs user interaction.

Anyone else experience this or was this just an issue in my browser?

same here
it opening contest window instead of missions, then no mission is selected, ut when i open manually missions iwindow, mission was automatically selected.

it will not do any thing for me i have even cleaned my cookies to see if that helped and it did not so its completely broken for me

Haven't been able to deduce what is happening so far. Seems I always have to select the first mission or visit the missions page and sit a while to see it activated and continue

Re: @twelve27:

Pretty sure they are considered as the same initial page and that may be the problem.

Re: @3jameo3:
That could be it. Sometimes it looks like it is going to the contest page and does not pick up a mission. And sometimes it looks like the contest rewards aren't collected as well. Wish I had more free time to look into it. Been relatively busy with stuff so I can't debug and play around with other solutions
