It is not consistent in saving data to meta or data. Only in your plugin. Sometimes it does and sometimes it doesn’t. One other strange thing…when I succesfully saved the data or meta and I want it to be visible on a wooproduct, I have to reconnect the ppom settings to the product or else changes are not visible.
And third strange thing…when I use quantities and set the price at 5 euro, it is not using the price of the quantity but the main woo-price. Even when it is left empty it charges the main price times the quantity. Check my link
Strange don’t you think? Before the update this part worked well for me.
