As everyone have already noticed, Since latest update, BIS only resolved 5 issues. (lets make it 6)
I do not know, but if you go and filter out all the issues by status "assigned" you will see 20 pages of assigned tasks!
Now, we know each page views 50 issues, so 50 x 20 = 1000 issues assigned! (maybe a little less as on the last page there is little below 50 issues)
Now if BIS continues solving only 5 issues a month, this is what will happen!
1000 / 6 = approximately 166 months! (A little bit below 166 months as the last page had below 50 issues)
This is how much time will need to be spend to resolve everything!
These are only assigned tasks, you have as well tons of under status of "reviewed"!
Keep it up! You got a lot of work to do, otherwise unassign the stuff you will not fix, because it's pointless keeping it assigned... Only blows peoples expectations...
