"How can I ensure that when adding a new disc title, the complete and most up-to-date version is downloaded from the server?

I have encountered a recurring issue (five times now) where I add a film box set via the app, but it isn't recognized or displayed as a box set. Consequently, I’ve spent hours using the Windows version—manually scanning about 10 discs, scanning covers, and typing in descriptions—only to receive the following error message when trying to contribute:

'You cannot contribute this title as it represents a box set in your collection, that is different from the one found on the server...'

This indicates that a box set already exists on the server, but for some reason, it isn't being downloaded or updated correctly on my end. Why is this happening? What am I doing wrong, and how can I force the app to pull the existing server data?"

No these titles are older boxsets. For example I added the "Fassbinder" box set (4006680079288) last year in November by scanning the barcode with the app. It was not displayed as a box set although it already was a box set on the server since 2019. I don't know why.

At least in the Windows version, you used to be able to select "Update title from server" or something similar. I can't find that option anymore, though. So I don't think there's any way to do it anymore.
