Carriers are also notorious for taking at least 6 weeks after the release of a new build to test it for compatibility with their networks, especially re. 911 calls. And with different 7.0 updates seeping in from OEMs, they probably dumped 7.1.1 on a backburner anyway.I haven't read about anyone receiving the OTA update so far - only about people sideloading. It may be that the OTA was halted because of the speakerphone bug, but no one seems to really know what is going on.
....So those of us who are too lazy to root
FYI, the rooting comment was in reference to getting Google Assistant on the N6 not to sideloading an update.
