Oreo update broke fast charging G5 h820

So I just bought a G5 (H820) a few days ago, updated to oreo yesterday. I am on AT&T prepaid. I used it for one day with nougat, it seemed to charge very quickly on my Aukey Qualcomm Quick Charge 3.0 charger, along with some nice usb c cables I have. I also have a nextbit robin, checked Ampere on the Robin and I see 2300ma of charging current. On another generic 5v2a charger, the robin sees 1600ma current.

On either charger, my G5 is topping out at 970ma. Ampere lists the Qualcom Quick Charger as "turbo" speed, and I get a 'fast-charging" notification. I tried restarting to no avail. Pretty clearly a bug with this release and I have no way to roll back.

I should also note that I immediately did a factory reset after the Oreo update finished yesterday, to limit any potential bugs.

It took an hour to go from 5% to 50%, which is definitely not fast charging, as can already be determined from Amperes current reading. 

"The LG G5 supports the latest Quick Charge 3.0 standard, but there seems to be a bit of confusion about how it works. It's designed to charge your phone quickly, taking it from 0 up to 80 percent in around 30 or 35 minutes.
