Payment window not working

Hi @tommy96

Can you share with us more information on how the issue is happening? You may use https://snipboard.io when sharing screenshots, then https://www.loom.com when sharing screen recording.

In the meantime, I suggest performing a conflict test by switching to a default WordPress theme, and then deactivating all plugins except WooCommerce and WooPayments then test an order to see if the issue is gone, if yes, that means a theme or a plugin is contributing to the issue. Re-enable each to see which one causes it. You can find a more detailed explanation of how to do a conflict test here.
