I have exact the same issue in all browsers. I have created 6 different modals for my 6 rooms. Every modal has a unique id and I have update the custom.js for the other 5 room-modals. At first, I click on the first room and the modal is open with the complete content. But if I close this modal and open the modal of room 2, then the gallery in the second modal don’t work. The other way: If I reload the page and open the second modal at first, the gallery works, too. But If I close the second modal and open the modal of room 1, the gallery in the modal of room 1 doesn’t work. Every time, the gallery works only in the first opening modal. Have you a complete code example for working with more room modals? Because in your template, you use everytime only the #myModal1 for all rooms. But this should work although with unique modals for the unique rooms.

Before purchase i want to tell you about an issue i see on the demo. Once you click on BOOK NOW on one of the rooms, the gallery shows correctly. If you close the gallery and then you will choose another room gallery it won’t work.
