so I installed nordVPN on my galaxy tab a SM-T580 and left it active for around 10 hours. When I turned it off and tried to use wifi as normal, nothing would work. The wifi showed it was on and connected but it would not let me use anything requiring network. I then proceeded to uninstall nord and cancel my subscription to no avail. I looked up trouble shooting options and tried it all and nothing worked. Last thing I tried is a factory reset of the device which still did nothing. In addition i tried to connect it to several differet networks and it still didnt work. Please help.
