I really am becoming frustrated with the cables. No matter the brand, I have terrible luck with them...besides the ones that go missing because of my kids...the others just stop working...or never work properly to begin with. I always buy mfi certified cables. Half the time they only work when put in in one direction. I bought cables as stocking stuffers for my kids and two cables... didn’t work both ways right out of the box...in my devices and brand ones received that day. What causes the cable to have this issue? I have it with a few other cables. Anything I can do to fix it?
