A. 1. Ensure that you are using the latest version of the app by checking for updates in the App Store. 2. After updating, try using the sort by price feature again. 3. If it still doesn't work, try clearing the app's cache by going to Settings > Home Depot > Clear Cache (if available).

B. 1. As a workaround, manually sort items by price by viewing the product listings and noting the prices. You can also use the website version of Home Depot to sort by price if the app continues to malfunction.
