Crushes review for Discount Master ‑ Quantity

The discount campaign takes a long while to apply to all the products. Even worse, once the campaign was finished, I checked in on the website and about 30% of the store still had the applied discount (even though we had emails saying it had reverted to the original price, and the campaign was ended). I tried to fix this by deleting the campaign itself in hopes that would return the prices, which it did not. So spent over two hours having to manually return the prices one variant at a time on our website. One of the worst shopify app experiences I've had to date, would not recommend to any large inventory store
