Different Account Issues across Devices

I'm having problems logging into my apple account on different devices. My iPhone will not let me enter my email or password to purchase anything in the App Store, Music, Subscription(s). My Powerbook won't except my password for a few Apps I need to update on this device. My iPad appears to be working/accepting my login to the account. I've used it do get what I needed and sync them, but I still need to fix the problem.

I had changed my username/email, a week or two ago, The only cause I could think of that would trigger this, but not sure why my iPad is the only device working to access the Items/stores in the apple account?

iPhone 16 Pro, iOS 26

First thought is sometimes people don't actually change their addresses but instead create brand new accounts. The support article https://support.apple.com/109353 outlines various methods for changing the email address (Apple ID) you use for your Apple Account while retaining everything in your account.

Second thought is to restart the devices and/or sign out of accounts and back into them. Sometimes they are slow to get the message that account sign-in information has changed and are still using old information that is no longer valid.
