Thank you for your feedback!
Is the Logitech Media Server a software dlna server on your pc or a standalone hardware drive?
If its free and installable I can try to test it…
Spotify integration is on my roadmap, but thats not so easy because of some license and api questions. I don’t want my app to be banned from the playstore. 🙂 If there is any progress, I will let you know.
iOS support is also on the roadmap but I can’t tell you any release dates yet.
