methodman89 I deleted the VPN setup as you said and followed those steps but its still not working.
A few things I have learnt during this time
1. My ISP router (GPON fibre router/modem) also has wifi. I have tried directly connecting to its wifi rather than the TP link access point, but the apps still not dont work.
2. Also the web version of these apps like twitter, amazon are also not working on the Wifi as well (the homepage just loads partially and nothing else happens). This probably means my ISP has some issue with the android platform particularly Samsung and Sony Bravia (since its only affecting my Smart TV and Note 9 and not Apple Iphone and One plus 7)
3. Now whether the issue is at the android level or ISP level? I feel that since all this apps work fine on laptop, iphone, one plus 7 with same Wifi its likely to be at the android level
So what settings/ports maybe for the android I need to make is something that needs figuring out...
