"Broken checkout experience" - google merchant suspension

[mm44-9]

Hello

my site https://millenniummachinery.ie/collections/menu/products/collet-chuck-set-mt4-er32

has a problem in Google merchant center for:

"Account suspended due to policy violation: Broken checkout experience"

https://support.google.com/merchants/answer/9158778?hl=en

Can you help what is missing form my checkout process?

Google says:

Ensure it’s possible for a user to checkout starting from your landing page and make sure the checkout process on your site is straightforward. This includes a working and easy-to-identify buy button.

Because, you are forcing a user to enter an apartment/suite, which obviously not everyone has. Make this field optional.
