I have created many ads, how can I choose the active ones? and delete the old ones? There is no function to select or sort them! 
I’m not sure but the first thing I think of is maybe try the checkbox on the left, and see if any prompts show up. If you’ve already tried that; although I’m not quite sure what your goal is; try turning off the ad? I apologize if this is off-topic, I’m just not very set on what your goal is.
I want to select by the “status” or sort them. But now I have to browse many pages to find the active ones.
Ahh i see. If you select the tick-box on the left? Does it prompt any options?
