Using Ethernet for controlling - now problems

My Hifirose RS250 is connected to Ethernet. I use my Android phone with Rose Hifi App connected via Ethernet cable + adapter to control my RS250. This has worked really fine, until the last update. Now the app craves Wifi. Same problem with the new App Rose One.
I can still use my Windows Laptop via Ethernet.
I have no Wifi for health reasons.
Please advice!

To keep using this device, you probably need to stay in the 21st century. Otherwise, just buy an old gramophone and listen to music on that. Or stop using your Android phone altogether. Modern streaming devices are built around modern network standards!

Ethernet is a perfectly fine and modern network medium. More importantly, the app should not care the least bit how the phone connects to the network.

I would put this in the Support section and tag one of the Rose employees.

Please check the following:

  1. Please let us know the software version of your RS250.
    RS250 → Settings → System Info → System Version Info → View Details → ROSE OS
  2. If you uninstall and reinstall the RoseConnect app on your Android phone, does the same issue still occur?
  3. Does the same issue occur even after rebooting your router?
  4. Does the same issue occur even after performing a factory reset on your RS250?
    RS250 → Settings → System Settings → Factory Reset
