This has always been possible with the desktop file manager integration of WD Discovery. But since WDD will no longer be further supported after June 2023, there must be a different solution and there is: This has been possible for a while now if you are familiar with Tailscale and its subnet routing functionality that allows native desktop file manager integration as well as mobile app support using any third party file manager such as Android ‘File Manager +’ which has network SMB LAN support.
Tailscale subnet router installation. Tailscale is free for personal use.
An example of My Cloud Home (MCH) mch4 private share tailscale copy (upload) remotely. Copy of Public LAN share is also possible, all remotely with mobile 5GUC data in this case. Typically at 600 KBps for small files, 1.5 MBps for larger files which is near the limited upload speed for this 5G data plan.
Below is an example download of an entire fiolder from MCH to a remote Android mobile (5G data) via Tailscale subnet routing of MCH without using the My Cloud Home app or WDC relay servers
