I hope you all having a great day.
Here is the deal, whenever I load a lot of products from API that has one image each one of the products, the app kind of does a restart, and it loads from the beginning.
In the beginning it was with simple <img> tag, I changed it to ion-img, and I saw that there was a big difference using the ion-img tag because it lazy loads the images.
But still, when I have loaded more that 40-60 products, and those images are loaded, the app still refreshes.
I remove the images, no images are shown, and the app works fine, but the app needs those images.
What might be the issue here? Am I missing something?
Click Here for Streamable 1 video
Here the client wants to see product categories with a lot products in it
Click here for Streamable 2 video.
Here the client wants to select a product, but when it does, the app restarts.
The second video, is where I have tried, to remove the top 15 products, when get the next 15 on infinite scroll, but a scrolling flick happens because of that.
Here it is Ionic Info:

</ion-item>
</ion-col>
<ion-col size-xs="6" *ngFor="let prods of sub.products">

</div>
</ion-card>
</div>

</ion-col>
</ion-row>
</div>
</ion-grid>
This is the error I am getting on XCODE when the crash/restart happens:

Thank you very much.
The issue was the HTML TAG <ion-card>.
After I removed that tag, and replaced it with <ion-grid> everything was working fine on iOS.
But, thanks for letting me know about ion-virtual-scroll @E. maginni , I will give it a try and use it in the future.
