I want to say that this versión 3.18.3 is stable, but I have had a lot of problems with Delay JS execution. They are making big changes on the algorithm (version 2.0) and it doesn’t work with famous Porto Template 7.4.4. Be careful and I recommend to deactivate the delay. Because they have implemented a module script to repair, but it is very new and I have tried it but it doesn’t work with Porto. With the delay you will not see image products or descriptions until you make a click or a move in the page. New versions of Porto Template could solve this, but newest 7.4.5 doesn’t work.
Thanks for the contribution.
