Hi ccharat,
Welcome to the Apple Support Communities! It sounds like you did a good job editing your Apple ID and primary email address, but you didn’t sign out of iCloud on your iOS device before hand. What you may need to do in this situation is go back to the Apple ID website and edit your Apple ID and primary email address back to the email address that is signed in with iCloud (there is no need to verify the account after editing it back to the old account, just changing it back is enough). Once your Apple ID is back to the original account, delete the iCloud account from the iOS device and be sure to keep all info on the device when prompted. After you delete the iCloud account, go back to the website and edit your Apple ID and primary email address back to the new address. Once it is back to the account you would like, you can sign into the iCloud on the iOS device with that new account and merge all of the data when prompted. Please use the following article as a reference.

Change your Apple ID temporarily
If signing out and back in to iMessage or FaceTime didn't help, try these steps:
Change your Apple ID to the Apple ID you used previously. You shouldn't need to verify the email address.
Go to Settings > iCloud. Complete these steps only if the Find My [Device] setting is turned on:
Scroll down and tap Delete Account, then tap Delete to confirm.
Tap “Keep on My [Device]” or “Delete from My [Device].” In either case, your data remains in iCloud and will be updated on your device when you sign in to iCloud again.
Enter the password for your previous Apple ID.
Change your Apple ID to the new email address that you want to use. You'll need to verify the email address.
Return to Settings > iCloud and sign in with your new Apple ID.
I hope this helps,
