Hey Ben,
Regarding my comment here I’ve just found a weird behaviour : while adding a simple diaporama in a row, it only displays after clicking on Finish.
Can you replicate this issue ?
Best regards,
Frank
Hey Frank,
Thanks for getting in touch! I can’t seem to replicate the issue from my end. I tried it via the normal row and global row and it refreshes every time I change the gallery items. It could be caching that’s causing your problem. Do you have any caching plugins installed? Better yet, have you gone through the plugin deactivation route? Let us know how it goes!

Hey Frank,
Does that mean we can disable the other plugins on the site, change themes, and etc.?
Ben
Yes you can
Hey Frank,
You can disregard my previous reply. I’ll be submitting a bug report for this. Thanks for the heads up!
Ben
