It seems that there is currently a conflict between GeneratePress.com them 2.3.2 with the default them of WooCommerce Multi-Step Checkout by SilkyPress.
I ran into a problem scrambled credit card payment fields at the last step on the PC screen using Chrome and Microsoft Edge browsers. I deactivated WooCommerce Multi-Step, and the page looked fine afterward.
If you have a solution to this, please let me know to reactivate it again.
Kindly test it and help find a solution with the plugin provider.
Can you creating a staging version of the site so we can then take a look?
GP uses standard woo templates so there should not be any conflict, especially with Credit Card fields as they are specific to the payment service you’re using.
