I don’t know about the discount and review thing. But I can assure you that my comment here is not paid or asked for.
I tried this plugins on a couple of sites and it just works. I double-checked everything and it’s correct.
The developer creates very good plugins and he drops them free of charge. You can buy a pro version and support him.
If you don’t support him by buying. At least you can thank him or give him a good review. And if something isn’t working, create a post in the discussion section first.
This message is not written by AI and nor am I friend with the developer. I’m just a person that cares.
Thank you.
