Spotify Player on Wix – “App not loading” error when connecting playlists or albums

[Quix98]

I’m using the Spotify Player app on a Wix website, but when I open the app settings to connect a playlist or an album, the app fails to load and shows the error message “App not loading.” I’ve already tried using different browsers, clearing the cache, disabling ad blockers, reloading the page, and uninstalling/reinstalling the app on Wix, but the issue persists. The player itself installs correctly, but the problem occurs specifically when the app attempts to load Spotify content, which makes me suspect an issue related to Embeds or Web API authentication/permissions rather than playback. Any insight or known issues with Wix integrations would be greatly appreciated.
