After editing a scanned product for its price, why am I no longer able to see the Promotion applied?

If you edit a scanned product on the transaction grid, for its price or discount, the promotion applied is removed.
To be able to set up and configure in-store offers and promotions you must activate the Offers, Discount, and Pricing Management plugin. Promotions configured in the application are set to apply automatically when a certain condition is met.
Plugins in Tagrain are either Subscription Based or License Based. So the price that you pay for your plugins is based on the number of POS terminals that you have in your setup and the number of licences that you have acquired.
There will be no change in your subscription amount in the current billing cycle if you are only deactivating the Offers, Discount, and Pricing Management plugin AND not updating your Store / POS count.
