Hi Patrizio,
The latest update addresses bugfixes regarding the checkboxes, the slider as well as the isotopic list behavior, it had been just released in the past few hours.
I suggest updating it firs, then clearing all the cache as well. The checkbox trigger issue should immediately go away, as well as the slider should get more responsive.
The performance issue however does not depend on the device, it may have only been a temporary server/ISP issue, as I just checked and it works very fast at the moment, from my end. Make sure to clear all device cache as well. Let me know how it goes, and if you need any changes still.
Best,Ernest Marcinko
