Hi francoisgernigo!
Happy to help with this!
In Storyline, 360-degree images are touch-responsive when viewing a course on a touchscreen device. No special settings are necessary. I published a sample slide to Review 360, and opened it with Safari on my iPhone. I was then able to rotate the 360-degree image with my fingers.
Do you mind sharing more details on the device you are using? It would also be helpful to know how you published your Storyline course. To Review 360, LMS, or to the Web?
If you're comfortable sharing the .story file you've been working with, please upload a copy here in the discussion or privately through a support case. We'd be glad to test the behavior on our end!
