You're just not paying attention. They've wrapped up their investigation of the problem, they've conclusively identified it and figured out how to prevent it from happening again (both through more thorough part testing and through beefing up the specs on the particular component so it has even more margin in a "belt and suspenders" approach). They've bundled their mitigation techniques into the roll-out of the next iteration of the F9 (sometimes called the v1.2 but officially called the "FT" or "Full Thrust" version) which will be the version which gets launched from now on. They've done a static fire test on the first stage that has a planned launch in early December and they've done all the other prep-work for a launch then. It's very likely that if the weather cooperates they'll have a return to flight within about 3 weeks.
