I'm having trouble with pages loading initially to the background colour, despite setting poster images on all videos.
I'm exporting to xpub, and the behaviour is different in different languages.
When I try to create a poster image using a video frame I get an error message (I think this is happening since the last Pubcoder version update?).
I had previously saved images, so I am linking to an image from the asset files.
I am setting the background colour to #000000FF for images and videos (if it has to appear before the image or video, I'd rather white than black).
I managed to get the Spanish version in the xpub working properly, I think by unlinking and relinking all the poster images, but then when I went to do the same thing in the English and French versions, it didn't fix those and it corrupted some pages in the Spanish version again!
