Using Odoo 10 Enterprise with multiple companies and have begun setting up shop items for each company.

While the public can see the /shop page, a signed in user cannot. It returns the following error.

AccessError: (u'The requested operation cannot be completed due to security restrictions. Please contact your system administrator.\n\n(Document type: product.pricelist, Operation: read)', None)

Looking at Security rules, those around product.pricelist seem to be correct

My default user has Public and Portal Access and is linked to the right company. What am I missing?

UPDATE: This problem only seems to be relevant for the second company. I have two companies with two shops and individual products. Company A works fine. Company B does not showing the above problem.

Thanks
