Pietra: AI Product Designer

I was excited to use this app. I even plan on paying for the subscription but I can't try out the app without first paying for the subscription. The app gives you a 24 design trial which only works if it was 24 designs that are saved to your store. No that's not how it works the 24 design limit is for each time that you click on any product to look at it or try one if the a.i design functions. So I used up my 24 design limit just looking around. I still don't know how the app works and am so frustrated now that I just want to uninstall the app and forget about it. The free version which is not the same thing as a trial. A trial is a period of time to use the app and try it's functions. A free version is the ability to use the app with limited functionality with the option to upgrade.
Please fix this. If you're offering a free plan change the 24 design limit to a 24 uploaded to your store design limit. As it is I still don't know what your app does or how it works.
