Removed Apple Cash card because funds were not showing up, now I can’t re add it.

Hello Liam_Ca,

Thanks for that info and for choosing the Apple Support Communities. If we understand correctly, you are unable to setup Apple Cash again on your iPhone, as you get an error. If you haven't already, please restart your iPhone, check if there was a recent issue with that system, and other steps from these Apple resources:

If your Apple Cash account is restricted or locked

If you can't send or receive money in Messages with Apple Cash

Set up Apple Cash

Cheers!

My daughter is having the same issue. She had received an apple cash payment and the transaction showed up, but her balance didn't update. She tried signing out of icloud and back in. Now when she tries to turn on Apple Cash it tells her to sign into her icloud account, when she does, it just says there was an "error setting up Apple Cash". Doesn't say what the error is. She has tried turning the phone off and back on, she has tried logging out of icloud again and back in. Still unable to turn Apple Cash back on. Her phone (iphone13mini) is up to date (of note, she is under 18, but in our Family Sharing account she is authorized to use Apple Cash - & I can see the correct balance of her account.)
