Hustle popup won't stop popping up

HI Support – we are using Hustle for a basic popup and no matter what changes we make to the popup settings it shows up on every page, even after dismissed or selected to “never show this again”. I know you will tell me to turn off all plugins, etc but frankly we’ve run into this on a number of sites with Hustle and it would be helpful if a: you could provide us with some idea of what conflicting plugins typically are and b: address this within the hustle plugin itself – I’ve had to move a number of clients back to SUMO. Please advise or help us address this.
