Bought a set of cables on aliexpress. One side is fine, the other side is unattachable. I pressed really really hard and it won't snap in. Visually to the unaided eye, both sides look identical.
Ever have a faulty MMCX connector?

We have seen this happen before, not often but it does occur. Its really bad when they are stuck on and you cannot remove them!
