I can still close whispers, even with offline people.
I did it not an hour ago.
I’ll check tomorrow and see if I can reproduce this bug.
Please in the future note that their is a “Bug report” section of the forums where this might be more appropriate.
Actually, a relevant post in that section (Bug Report - Heroes of the Storm Forums) may still be valid. Just, please, PLEASE, first read the article of writing a good bug report (Bug Attachment Guidelines)!
thank you
