The addon works perfectly and exactly as described. To improve: from my point of view when submitting the addon, it should include some kind of instructions of 1) How to install it, and 2) Basic problems that the user can encounter, as then you spend a lot of time with Xenbros chat support with the problems that you have. However, their support has been excellent through the chat and they solved all my problems quite quickly. So a very good purchase!
So far working well on a shared Litespeed server at Veerotech hosting. Server resources have dropped considerably from my older VPS. There was an issue with some desktop/mobile settings with another plugin, but Michael at Litespeed responded very quickly with a fix to resolve the mobile cookies/caching issue on this discussion thread.
