How to clear cache from iOS app users when an update is released?

Question

Android

Released an update to the ios app. For users who updated the application, many things stopped working.
At the same time, if you do not update, but delete the application and install it again, everything works fine.
Tell me, what could be the problem? How to properly release app updates?

Answer 1

Perhaps you changed the structure of the database and did not migrate.
There is no cache that could harm in iOS development.

Answer 2

2 scripts are usually responsible for changing the text on the button in the cart:
1. For the product card, search for the script in product.tpl by $('#button-cart').on('click', function() {
In your template, these the lines are actually responsible for the replacement itself: 2. In common.js, you have /catalog/view/javascript/common3.js addToCart function, line 163:
$('#cart-total').html(json['total']);
