Hello MoTaRdO,
Welcome to the Community and thank you for posting.
I am very sorry to hear you are experiencing an issue when trying to un-pause your wife's device.
Are you able to access the Hub settings as per Client62's suggestion to check if the device is listed as blocked there?
Also, we would recommend fully signing out of the app and back in to see if this removes the error message.
Let us know how you get on.
Thanks,
Nat
