There seems to be nothing attached to your reply - feel free to also instead upload the files to wetransfer.com for example and then share the download link afterward if you cannot attach them here due to file size.
Please have a look into this because it is happening all the time. And each time I have to close the main file, open it again and reattach the worksession file for the materials to show up. And this is a major waste of time.
Please let me know if you are able to replicate this bug.
@FloatingVolume , thanks a lot for the files. We were able to reproduce this behavior accordingly - our developers are still busy with finding a solution and are also analyzing if this can be resolved in general, so thanks for a bit more patience in that regard!
