I've decided to lower my score from two stars to one. I used this plugin for three years with no issues until now, which was why I gave an additional star. However we started experiencing bugs and I purchased support to fix them.
The support team will not respond to requests, despite having paid for it. Because of this I was forced to buy another plugin, which works great for us.

I am currently seeking a refund for the extra support I purchased. I recommend that if you need a variation table plugin that you do not purchase this one.
