    Filed as issue #4711 on GitHub.

  • Confirmed

    Reproduced by a maintainer.

  • Closed: won’t fix

    Handoff is for sessions, not for moving big files. Files over 4 GB now show a clear message and a link to Luma Sync’s file transfer, which handles them properly.

Reproduced on my machine on 1.4.2. Same steps, same result.

Thanks. Labeled and in the queue. If you can attach logs from the help article it will save us a round trip.
