I have the PRO version and have nearly 1200 products in store. When I click on preview prices, only one or two product’s converted information is being shown, and when I scroll down the page becomes unresponsive and a loading symbol is shown eventually. I have also tried different block sizes and time limit settings. I have nearly 875 products in another store and there the prices are previewing and updating fine with default options.
Can you try applying the bulk edit to specific category (then 1 by 1) to see if that works? Maybe this will be easiest solution, if it didn’t work, I might need to login and see, please contact us at [email protected]
