Ultimate Upsell & Cross‑Sell

Used this app for a number of months now and never been very pleased with it. The main issue is that the pop up is soooo slow to load so customer's have already moved on before it comes up.

Also there's lots of issues with it not working if you try to include it in-theme. Particularly at checkout it didn't work at all

And the analytics don't track well. It regularly counts purchases where none have occurred and there's no real analytics dashboard so you can't go in and scrutinise how well it's doing
