Regarding the cable issue, once had that happened on a sram x01 11speed system, the shifter paddles would move to a certain extend but nothing else was happening. The cable end dislodged itself from where it's supposed to rest. After examination the problem wasn't from the shifter ,nor the cable, nor the derailler but from the old and maybe a tad short housing that was creating too much friction in the system. By trying to downshift multiple gears into a harder gear (smaller cog size), the derailler return spring wasn't strong enough to push back the cable in the housing due to the friction, the derailler would barely move down, the cable end pop out from where it seated and jammed itself in the shifter. After replacing the cable and housing it worked as new and still works today.
