Immersive Frames

when I go to update my comic and add a new page and add immersive frames, it suddenly says cannot load release on mobile. when I delete the immersive frames the error message goes away, and you can view it again. 

this issue only happens on the mobile app. when I view the comic with immersive frames on mobile browser or desktop it appears fine, no error message. I replicated the issue on my husband's phone (in the app) as well.

I deleted all immersive frames and it seemed to resolve the issue, but this seems like a bug. Please help! I miss my immersive frames
