Pop up ads

I got this app a month or so ago and have really liked it until today. When I opened the app today I got a pop up to try one of the developers other apps. I’m not able to do anything with Weather Live unless I click on one of the buttons. This ticks me off! I paid for the app so it shouldn’t be held hostage by a pop up ad. I shouldn’t be getting any ads! I will not be purchasing any more of Apolon’s apps.
