Source shown in Spotify App, but not in HA Integration / Spotify API

[Alwinator]

Problem/Motivation

Everything worked fine for a long time until I updated HA. After that I could still use Spotify Connect without a problem, however, the device was not shown anymore in the Spotify Integration. I first assumed it was an issue with the integration (see https://github.com/home-assistant/core/issues/97867), however, after writing the following script I found out that it was the Spotify API.

config.yml

auth_manager:
    client_id: xxx
    client_secret: xxx
    redirect_uri: http://localhost:7777

test.py

import spotipy
import yaml
from spotipy import SpotifyOAuth

with open("config.yml", "r") as stream:
    config = yaml.safe_load(stream)

sp = spotipy.Spotify(auth_manager=SpotifyOAuth(scope="user-read-playback-state", **config['auth_manager']))
print("Authenticated as {}".format(sp.current_user()['display_name']))

res = sp.devices()
for device in res.get("devices"):
    print(device)

Expected behavior

The device should be listed in the Spotify sources.

Actual behavior

There are two devices listed, however my HA Spotify is not listed.

{'id': 'xxx', 'is_active': False, 'is_private_session': False, 'is_restricted': False, 'name': 'My PC', 'supports_volume': True, 'type': 'Computer', 'volume_percent': 100}

Steps to reproduce

1. Setup HA with Spotify Connect with the same versions
2. Use my attached script

In my opinion the logs are looking fine:

It also works with the official Spotify app.

Not sure what the root cause was, but this bug magically fixed itself. I assume it was a bug in the Spotify API and was fixed by the Spotify team.
