You can use initWidgets to reinitialize ratings and reviews from Yotpo if you use javascript/ajax to load new content.
If you for example use javascript/ajax to display more products to the user you probably want to reinitialize Yotpo star- and review ratings as well.
Out of the box Yotpo only supports loading them on the first page load. But there is an undocumented method called initWidgets() that you can invoke instead of reloading the page.
javascript
You can invoke initWidgets() like this:
yotpo.initWidgets();A big thanks to Richy who also had this problem, found a solution to it and went back to stack overflow to tell others how to solve it.
