If I convert my images from jpg or png to webp in the designer, any lightbox gallery I have using those images no longer works. If you open it about 90% of the images are no longer there and you just get a white spinning wheel.
Got the same issue. Lightbox works fine on the internal site but it’s broken on my exported version. I think the newly created webp files are not being exported.
I put in a ticket … trying to figure out the fasted way to fix the issue.
