I have 500 mbps fiber setup at home installed a week ago. I have found that on android note 9 certain apps like netflix, twitter, prime video, amazon shopping (But Youtube works) dont work. But they work fine on mobile internet. Running these websites on my laptop they work fine over wifi. I also found that my sony android smart tv is facing the same problem with the same apps not working.

I tested these apps on an Iphone-they worked fine. They also worked fine on oneplus7.

I have rummaged forums and platforms trying to solve this problem but no help so far. My wifi setup is as follows:

GPON Router/Modem(given by my ISP)----TP Link Router Archer A9 (Setup as an accesspoint)--- My android device

Also on my phone by using a vpn I gain access to these apps and also while using them on a mobile browser like chrome they work fine with the wifi. But apps dont work on wifi :(

Pl help guys
