Cob webs growing

I bought the lifetime license almost 2 years ago as it sounded enticing and this plugin has some good features. There was a blog post just a few days before. I sent a thoughtful email but kept it brief. Crickets chirped. The first sign of an abandoned plugin. Some plugins go a year without updates which is fine. But after nearly two years and no responses it’s becoming more clear. Now there are errors in the backend which may turn to breaking functionality.
