Apple Remote won't connect to Music library after upgrade to Big Sur 11.4

Hello sumyung gai! Thank you for participating in the Apple Support Communities.

We understand that the iTunes Remote app is not working to control your iTunes library on your Mac from your iPhone. We'd like to look into this with you to see how we can help.

First, let's make sure all the necessary steps have been taken to set up the iTunes Remote app to work for iTunes on your iMac: Set up the iTunes Remote app for Music on Mac

If the issue persists, let us know if this also happens when trying to use the iTunes Remote app from another iOS device.

Make it a great day!

Hello sumyung gai! As mentioned previously, were you able to try the iTunes Remote app from another device? If so, does it work?

If it still doesn't work while using another device, does it work if you connect to a different Wi-Fi network?

Cheers!

Hello sumyung gai! Since the issue persists, connect with Apple Support to look into this further: Get Support

It is possible that they'll need you to test for this issue on another network to further isolate the root cause of the issue. If you're able to do that before reaching out to them, that may help.

Be well!

Same issue since upgrade to Big Sur 11.4 - tested with 2 iPhones on 2 different networks. Deleted all remotes in the Music app on Mac, deleted and reinstalled the app on iPhone: the app Remote can pair with the MacBook but is unable to connect to the media library

This is correct. After being on the phone with apple for 2 days (on and off) troubleshooting, they said that this is a known issue and that I will have to wait for this the engineers to fix the problem. I am able to control the music on my iPhone 11 Pro Max via home sharing, but not on my apple watch.

Same problem here. I figured out you have to enable „media Sharing“, that worked for me.

If you solved the problem would be nice if you share the solution here for all others 😊

Connecting from iTunes Remote using Home Sharing, rather than pairing with the passcode, worked for me.

Thank you MartinG8hR, this worked very well for me (enable Home Sharing instead of pairing with passcode)

Any updates on this one ? I still have the same problem.
