When I click "Add pre-order to bag" it tells me "Please make a selection for each option." I have quadruple-checked, and I have definitely made a selection for each option. What gives? Take my money!
Could you also write into support (though note that response may be delayed)? If you are logged into an account, the team should also be able to check the configuration that is in progress to see what is missing: https://framework.kustomer.help/contact/support-request-ryon...
I think there was something squirrely with my selection of keyboard options - I wanted two sets of spacers and a numpad, and on my phone I'd selected one set of spacers as primary and added another set of spacers plus a numpad. On my laptop, I chose numpad as primary and added two pairs of spacers, and that seemed to work.
