how do I upgrade???

I have the djay app and am trying to upgrade to the full version. I click on “learn more” and it attempts to take me to algoriddim’s website but wont load so it redirects me to the app store where it takes me back to the djay-Dj App and Mixer and has the “open” button. I press the “open” button and I am back where I started

Learn more redirect from the Algoriddim web site to the App Store page of “djay - DJ App & Mixer”. It says “Open” since you already have the new djay installed on your device. So that all sounds right so far. Now when you then tap “Open” and the new app launches, can you let me know what screen you are seeing? The upgrade from within the new app gives you 6 months PRO for free.
