I got a Homepod this week and setting-up is definitely easy, since I got two different Apple IDs, I signed into iCloud account with A, and try to sign into iTunes and App Store account with B which I paid with a Apple Music Subscription, but what I got is "could not complete operation" sign constantly, ANYONE can help! Many thanks!😢
P.S. I tried different iPhones and iPad which in the same HOME associated.
iPhone 7 Plus, iOS 11.2.6
Did you check the Getting started section of Set up and use HomePod - Apple Support, in particular the requirements for two factor authentication and iCloud keychain? Two factor and iCloud keychain probably need to be set up for both Apple IDs if you are using one for iCloud and another for Apple Music/iTunes Match/Purchases.
An observation from another thread is that you might need to have a valid payment method set up for purchases on the iCloud account, even if you're not planning to use it.

Many THANKS for those helpful hints, I double checked and I am pretty sure both two factor authentication and iCloud keychain are set for those two Apple IDs, and valid payment with both of my accounts. Any other great thoughts? Many THANKS!
One possibility is to remove the Home and Music apps from your device, then reinstall and try again. Otherwise reach out to HomePod - Official Apple Support.

Thank you anyway, since I bought this homepod from US to China, I currently cannot reach the Official Apple Support, I can just let the homepod to be a very very ordinary Airplay Speaker.
