After I upgraded my Max2Pro to V2.1.2 it stopped connecting to WiFi. Most of the times AP list doesn’t show up at all. I need to disable and enable WiFi a few times. When it does show up I am able to configure the network - then it connects and immediately disconnects from the network in a loop. Through adb shell I can see this repeating in dmesg (BSSID anonymized):
