So I've got a wifi access point here that I am able to connect to with my Huawei Mate 20 Pro. But it seems like the phone is not always actually using the wifi to access the Internet!? I noticed this when I was unable to start Youtube (I've restricted its use to wifi). But if I'm in flight mode and then only enable wifi, it DOES use the access point to access the Internet ( > Youtube works). So why doesn't the phone do this with 4G enabled? Especially since I'm standing right new to the access point.
