Hey fpats,
I realise this review is a couple of months back now, apologies for not seeing it sooner. We tend to be more active in the support forums.
We’d really welcome the opportunity to turn this review around, if you could open a support ticket and let us work with you then we’d be incredibly grateful. We would even be happy to give you a free membership to all of our premium plugins regardless of if you change this review or not, simply as a thank you for working with us to identify the issue you had.
I’m hoping we can turn your experience around along with the review. 🙂
If you’re happy with this then please open a ticket so we can start working with you:

Have a great weekend!
