Hi – we are having the same(?) issue. When we have enabled decimals, on a single product page, the quantity stays at 1 and cannot be changed at all.
Our settings for the plug-in are as following:
General
Decimal Quantities: Enabled
Minimum Quantity
Section Enabled
All products: 0.5
Quantity Step
All products: 0.5
We want to be able to sell by 0.5 units for all products. Can you please let me know what we have missed?
PS: This is on WooCommerce with CWMF. Single currency.
