Overlapping cart content with multiple store managers
I can see this question was asked and answered on Code Canyon about 3 years ago.
You introduced transients in shop as customers so that the issue with overlapping cart content was resolved, when multiple store managers or admins were useing the functionality at the same time.
We are running version 2.13 but it seems to be a bit buggy. We are experiencing just that, overlapping cart content when multiple store managers are using it at the same time.
