It was OK till I updated to the new version

Actually I liked the old version, functional and easy to use. After I updated the app a few weeks ago, it became a disaster. Every time you opened the app and/or tried to navigate it, it FORCED you to an advertisement. I have never used any app like this. After you open the app, it will directly linked you to some in-app ads. This is not the way to design an app and I have to remove this software.
