Importing images to C1 pro iphone Beta from sony ilce-1 via wifi

I’m testing beta C1pro for iPhone (IOS 16.5). Sony ilce-1 can be connected via wifi such that camera settings etc can be changed and captures taken directly to c1…however the images can not be imported via wifi. It seems that masstorage mode are not working with c1 while coocted via wifi. Br. Jouni
