I have had this problem for months and cannot find a resolution. Some apps will not load data from the internet over wifi, but are fine as soon as I stop wifi. All the time things like Chrome are working with no problems. Examples:
Weather - will not refresh
BBC Sounds - will not show content or My Sounds
Flight Radar 24 - shows maps, but does not show aircraft
In each case I just get the spinning wheel. These things all burst in to full life as soon as I drop the wifi. Also seem to work for an hour or so after a big network disruption (reboot router, drop and reconnect to wifi). I have the same issues on my current S20 and also on my old S9 - even after doing a factory reset and only installing the problem apps.
BT (my ISP) are sending a replacement Smart Hub 2, but I'm not convinced it is the router.

Thanks for the suggestion. Unfortunately this hasn't fixed it. I don't think it is an individual app issue as the same behaviour affects several independent apps.
Also that I get the same issues on a freshly factory reset S9.
It feels to me like an ARP or DNS problem; on wifi some packets are sent the 'wrong way'. Resetting the network can clear a bad cached setting, but it goes wrong again over time.
I'd like to be able to monitor my network to see if I can see badly directed packets heading out unanswered, or being blocked by the router, but network security and encryption makes that very difficult.
So is it:
- several individual apps having the same problem?
- virus or badly behaved app on the phone (doesn't explain the problem occuring after factory reset)
- Android issue
- Router issue
Its certainly got me stumped. And annoyed!
