i try to reconnect But the Mobile App show me this message

and I have only one way to connect to the internet: via mobile connection (hotspot)
How to fix. Please Help.

Hello,

To use the Rose Connect app on your mobile phone with your Rose streamer, both devices must be connected to the same network. To achieve this, the phone is typically connected via Wi-Fi.

Is it possible for you to connect an Ethernet (LAN) cable to your RS250? If so, you can temporarily use the RS250’s Wi-Fi hotspot (tethering) feature.
(RS250 > Ethernet > Tethering > ON)

Once the network connection issue above is resolved, we believe the Apple Music login issue will be resolved as well.
