Annoying pop up

[bgbagz]

So for the last month I have been having an annoying pop up at the bottom of my screen a gray oval shape with white letters which say "Free version delay". When this pops up, the app I am in closes and the phone goes to the home screen. Does anyone know what app is causing this?

Bro, did u install anything recently?
Another way is to turn off notifications of all unnecessary apps in your phone. And just update everything so that the pop-up wont happened.
