Just want to report that after having the latest beta 9.0.0.4.386.48966 for a week now, it still works great. No dropping connections and perfect WiFi all the time. Very happy I upgraded.
I came here via the closed topic ASUS ZenWiFi AX (XT8) Disconnects Wireless every 30 minutes. I know this forum is more targeted at laptops, but without it, I would have never found the issue. Hopefully, this topic does not get closed for that reason...
