New 17.1.2 software update

Since I installed the new 17.1.2 software update, my WiFi has been acting up and won’t work on certain app. For example Netflix, YouTube and others. I’ve researched how to fix this issue and tried everything. I’ve tried to turn off my phone and then back on, I’ve tried to turn off my WiFi and VPN and turned them back on and I also reset my Network Settings. Nothing has worked. Is there anything else I can do?
