When some customers try to checkout, they just get a loading circle which never goes anywhere. I have tried on my PC (running Chrome) & my mobile (Samsung Internet) & have the same issues. However, this morning I have taken one order paid via Paypal Express & another via Shopify payment so I am totally confused why this is happening. I have Limitisfy & Infinite Options third party apps installed.
Can anyone help? I've spent weeks having this site developed after migrating from Squarespace & thought Shopify was meant to be e-commerce friendly.
