We're sorry to hear about this. Please let us know if you replaced the picture by uploading it from the device or the Adobe stock images. Did you try signing out and signing in again? Is it possible for you to share the screen recording of the issue?
This happens straight away, before having the possibility to choose between stock or device images. This seems only to happen when I try to replace an image in an existing project. When I close and open the project, it might eventually work. When I try replacing images in a new project, there aren’t any issues.
It might be a problem in syncing with the file in the cloud I think?
