You can play dsd files with mconnect using the folder view.

The iinstructions are there. The preupdate step can be repeated as necessary.

Instructions are in the FAQ under HOW DO I UPDATE POLY TO FIRMWARE VERSION 2.0.0?

I assume this is accurate Post in thread 'Chord Electronics ☆ Poly ☆ (wireless & microSD module for Mojo) ☆★►USEFUL INFO on 1st PAGE!!◄★☆'...

It could just be a fix to stop the app crashing when the Chord server is down. We shall see

In Bubble go to Settings - Renderers settings - Select renderer Chord Poly - Gapless control. Works for me.

Bubble, Hifi Cast and mconnect all do gapless. I don't use Qobuz or Tidal so don't know whether it works for them.

This can happen if Chord's server is down

You could use an app such as Net Analyzer to see what Poly's hostname is. If hostnames are not resolved, then perhaps there is something wrong with DNS configuration on your iDevice or router.

Hi- Hi-Fi Cast is a good alternative to BubbleUPnP. It is easier to configure. UPnP Tools is a useful app which can tell you whether Poly is advertising itself as a UPnP server and renderer.

Have you selected Other Music Services in Gofigure?

Mconnect was updated to 3.3.72 a few hours ago. You've probably picked up the new version.

I would guess that the volume is being controlled by your iDevice. Check that "Link Device Volume Control to MPD Volume" is off in MaximumMPD settings.

Flagged up before. No solutions posted as far as I know. Post in thread 'Chord Electronics ☆ Poly ☆ (wireless & microSD module for Mojo) ☆★►USEFUL INFO on 1st PAGE!!◄★☆'...

I only have direct experience with Qobuz. You can stream Qobuz to Poly via DLNA with mconnect and BubbleUPnP. They both have Tidal support. I don’t see a way to stream directly from the Qobuz app. I don’t think there is any way to stream Spotify.
