Hello,

1) For the cart flows please check how it works with the default WordPress theme just to check whether the issue is with our theme or not.

Because this is something to do with the Elementor page builder and our theme doesn’t influence.

2) You can read our detailed documentation on the theme update in the following link:

3) You can consider our detailed documentation on the typography settings in the following link:

Best Regards.
