I continue to receive Google account alerts on removed devices. How do I stop it?

I removed 2 Android devices from a Google account. But I continue to receive Google Account alerts on both devices from Google Play services, whenever I change the account password. Why is this still happening, and how do I stop it?

1) I removed the account from the 2 devices in Settings > Accounts.
2) I also removed both devices from the Google account website: Security Checkup > signed-in device
3) The 2 Android devices still show up in Security > Your devices (but the remove button is no longer available. I assume it will hide the 2 Android devices after 28 days?)
4) Now the problem. Whenever I change the account password, both of the 2 Android devices continue to receive Google Account alerts: "The password for your Google Account XX*****X@gmail.com was recently changed. Learn More." The email address is hidden except for the first 2 and last 1 character.
5) On one device, I tried deleting data and cache for Google Play services and Google Play store. But this did not help.
6) I reconnected 1 device. Then changed the account password. The 1 disconnected device continues to receive the alert. The 1 reconnected device gets a login error alert and requires a re-entry of the new password.

How can I stop this?

You actually have to sign out of all accounts in old phones and kill autosynch in them too.

Thanks. All types of sync was already switched off on all connected devices, before removing the accounts. Sorry, what do you mean by sign out of all accounts? I removed the accounts from the devices by going into the accounts section in the settings in each device, and pressed "remove". I did not find any other "sign out" function elsewhere. I also went into the accounts webpage and in the security > devices, I pressed "remove" on all possible devices. I did not see any "sign out" function on the accounts pages.

I'm still getting the account alerts on the disconnected devices whenever I change the account password on a PC browser.
