You obviously missed my comment up above where I did address it, and ignored my question. Granted, you are very good at staying on topic (ranting about people changing the topic in this case) but not very good at staying focused for more than the 10 seconds it would’ve taken you to read my comment and, hopefully, work around this issue like I have.
In the January 2020 Android9 Update of FP3, the unencrpyted open WiFi bug is still present. When in flight mode, and having turned wifi on there, it only lists encrypted Wifis showing in the vicinity. As soon as disabling the flight mode the wifi list very quickly also shows (and re-connects of you already used that wifi in the past) unencrypted wifis again. Hope this gets sorted out quickly, I have been constantly using this on FP2 back then. thanks.
