I was trying to use share feature with image gallery and it seems it doesn’t work very well with Yandex Disk storage (actually I didn’t test different storages). It always says that folder doesn’t have images (but it does!)
Unfortunately we do not have a thumbnail preview optimization method available for Yandex Disk at this time, so the image gallery will not work for this integration.
Apologies for the confusion. I will change this to a feature request so it can be recorded by the product team.
