You switched business models and now you have 3 plans. When I bought it (maybe 2 years ago, don’t exactly remember), it was only one paid plan and a free one. I bought the paid one and it did not restrict any number of sites, so I am hoping you will still honor that, as I am one of the earliest subscribers.
I cannot use my API key anymore for your plugin, can you please ensure this is not due to your new price structure changes? I can’t use it anymore.
