I ran a DCT ad set for 72 hours and followed the strategy of Uncle Jimmy in the video below, but some texts didn't spend at all and 1 picture spend way less than the others. Can I just continue with the picture that has a Link CTR of 0.67% and the tekst that has 0.61% Link CTR? And did I do something wrong what caused the decreased ad spend? I am relatively new so I appreciate your help guys.
