Hi @28yearssonyexclusive, let me see if I can help out here!
Are you able to see which app the ads are sent from and for how long have you been experiencing unwanted ads? And if so, have you tried clearing data for the app that is sending the ads? This will reset all settings for the app in question which might do the trick. To do this, find and tap Settings > Apps > App name > Storage > Clear data > Restart the phone.
And if you are not able to detect which app is responsible for sending the ads, have you been able to reboot your phone in safe mode in order to see if the ads are produced by a downloaded app?
Try these measures and let me know how it goes!
