Mixed Reviews. Works, but missing "Extras"

Purchased over a month ago. Easy to set up and appears to be working, but I'm a little irritated about a few features. First, I have my machine scheduled to turn on and off nightly at the same exact time every day, with the same exact settings, including "backwards airflow" and "night mode." Most of the time, this works as intended, but some nights the machine has turned on and those two settings are off, despite no one changing them. It's easy to fix, but if I have them set a specific way, I shouldn't have to fix them.
The second issue I have is the lack of Air Quality Report. As previously stated, we've had the machine for over a month. During that time, we have had "continuous monitoring" turned on every single day, since day one, however the app continues to say "Report Unavailable." I've looked into troubleshooting and verifying how much data is needed, and we meet all of the requirements, so it's annoying we aren't receiving/gathering this information. I've seen Dyson comment on many similar posts,
"To successfully generate an Air Quality Report within the MyDyson™ app, your Dyson purifiers need to have run for a minimum of 12 hours a day for at least 10 days a month. Continuous Monitoring mode will count towards this, as it ensures air quality data is monitored and reported even if your machine isn’t actively running."
These requirements have been met for a while now, but still no report and no support past the standard shown above to help troubleshoot.

Bought this at the start of winter and am glad I did. One machine does everything I want. Purify and humidify. It is larger than I expected and I need to refill the water tank sometime twice a day but I am in Chicago so the heat is running.
I would recommend this to a friend!

Clean, purified and humidified Air!

I am very happy with the Dyson Purifier and Humidifier. It's efficient, works well (is not as loud as I thought and read in reviews), the Dyson app works very well just wish it had more explanations for each category recording but may have to do a bit more research. When air quality drops, I turn it on (purifier and humidifier) at the same time and it doesn't take very long to purify the home. The water tank is large and holds enough to last for a while, I'd say about a week for decent daily usage. The design is a bit bulky but it's an amazing machine that keeps our home clean and purified. I'm very happy with my purchase. In my opinion, worth the expensive price tag.
