Timewalking ques are still bugged if you try to que with more than one person. I had this exact problem last timewalking event; if i que with my friend, we can wait for an hour plus without the que popping. If we que individually, we get into the instance within the estimated time.
Its very frustrating to not be able to play content i pay for with my friends. This problem was the same as it was several weeks ago, and blizzard never addressed it on the forums, or in game. Please, fix this.
The post from the start of the last event, if anyone was curious Timewalking queue bugged (maybe)
