Just to give the problems i got.
I have an iPhone X with 11.3 (beta). I'm from Portugal and yesterday i received my HomePod that i bought from UK.
I turn on, setup as normal and ask siri to play something. After that, i enter on HomeKit and touch on HomePod. Said that was trying to connect but the HomePod is still playing some music. After this i try to use my control center on iPhone and i can't push it, seems a bug. I reboot my iPhone again, touch HomePod on Homekit and said: trying to connect and after that, can't use control center again.
I delete homepod from icloud, turn on auto-login on my wireless and can't connected. So, turn on again and i did it but it's still a little bit buggy.
So, i tryied HomePod on my girlfriend house, so today i will try it on my and see if everything run smoothly.
I guess homepod is fine and the problem is something from wireless, i'm not sure. I thought to downgrade iPhone but i guess it will be the same thing. I tried this things at 1:30 am, so was a little bit tired. Today i will try to do everything correct and if i can't i will try to contact support in Portugal (i'm not sure if they can help me...).
I know this is confusion, but i try to explain everything i tried. But if you have any question, ask and i reply.
Anyone got that bug on iPhone X?
