Movie connect vs CLZ movies thumbnail loading

When scrolling through the thumbnail image view of CLZ Movies gives a way faster/smoother experience compared to Movie Connect. When scrolling through your collection on Movie Connect it feels like every image needs to be retrieved from the internet and no caching is being used.

I don’t think that can be resolved.

The CLZ Movies is a mobile app, with all data AND images stored locally on the device.
Movie Connect is web-based software, basically a website that you open in your browser. ALL data, all images that you see are downloaded from the internet.
There are multiple levels of caching though.
