I unplugged and rebooted the router and it worked, my apps work on the WiFi again.
I never thought about the router since only my phone was experiencing problems.
Thank you
The Amazon app strangely started to work again after app preferences were reset, but unfortunately the other apps have not improved and still do not work with wifi.
The internet is working, it says it is connected but most apps are not working on wifi, so this is a issue with the phone since every other device works on the wifi.
