Just as a side note, my wife's Pixel 2XL never had a problem connecting to my hidden wifi before it was upgraded to version 9. The only thing that changed was her OS vers.
Yeah... my S8 works on my hidden wifi without problems, but I'm on Droid version 8. Its my wife's Pixel XL running droid version 9 that's the problem child. The bluetooth is acting up as well on her phone, but I haven't had a chance to look at that.
I have a couple of issues with your reply... if in fact what you wrote is true. 100 developers is nothing. My firm has a couple of hundred dedicated to a single in-house app. We don't have developers do their own testing either. Development shouldn't do their own testing. In my experience...
WTF????
I just figured this out on my wife's Pixel 2XL. The ****ty phone won't even stay connected if you hide the SSID once it's all connected and configured.
I guess it's obvious Google doesn't really give a F*CK about people's security. I've had my SSID hidden since the beginning of wifi...
