Orbi - Wireless Network not available or LED flashing white on Router or Satellite

Can we please have some feedback on the myriad of issues people are experiencing with the V1.12.0.18 update in the thread here:
https://community.netgear.com/t5/Orbi/Firmware-V1-12-0-18-Discussion/m-p/1326324 and in multiple other threads?
Here are a few of the issues, there are others:

• Ethernet throughput to internet maxes out at 420Mbps.
• Internittent satellite disconnects. 
• Internet connection dropouts. 
• The ability to disable either 2.4GHz or 5GHz removed without notice.
• The ability to change radio power removed without notice.
• Orbi app no longer shows the satellite.
• Orbi app now lists all connected devices as wired, no matter the connection type.
• QOS settings page is broken, all that shows is a speed test. 

I'm experiencing all theses issues on a RBK50, other users have reported the same. For a premium priced router, this really isn't good enough.

Also, can we please have the ability to disable auto-updates? 

Thanks
