I have been testing a new version 4.1.5 and it feels like this plugin is premium quality! Thanks for your work and time.
Issue: If a non existing (new) TAG is added all the existing tags will be added automatically (but it does not show on the front end), the error “Maximum values allowed in field Tags is 5” is displayed. I have tested this on my site and the demo site.
Please let me know than you push a fix.
