WoodWe review for PreOrder Now Backorder WOD

The main issue is that around 10-20% of my pre-orders are not caught by the app. So that means 10-20% of pre-order clients do not know that they are making pre-order. And the worst part is that every morning I need to recheck orders in order to highlight not informed clients and send them information about pre-orders manually. Though, I am risking with bad customer experience because they did not know about it before buying. I contacted support, they tried to fix it, but they failed.
