With the Sonos S2 app on an iphone my Arc was detected and connected to my home network, but will not connect to my new LGOLED77GX TV. I have set the TV sound to output to HDMI Arc, and in additional settings I set the TV to audio pass through and to HDMI eArc. The Gen 3 sub is connected to the Arc, also via the wireless home network. The connection between the TV and the Arc is an HDMI 2.1 cable, plugged into the LG's eArc terminal (HDMI 2), and the other end is plugged into the Sonos Arc. I have tried simply powering off the Arc, and also a factory reset of the Arc, but each time I try to connect the Arc to the TV the Sonos 2 app says it cannot connect to the TV when I tell it the Arc is physically connected to the TV as described above. Help please 🤔.

Disconnect the Hyundai box and the Arc from the TV. Re-run TV Setup in the Sonos app and don’t connect the Arc to the TV until the Sonos app instructs you to. Once the Arc is connected successfully, reconnect the Hyundai box to the TV.
Set Auto Power Sync to Off.
Set DTV Audio Setting to Dolby Digital Plus.
Set Digital Sound Out to Pass Through.
