Unable to add new Contacts on my MacBook Pro

Under ‘Accounts’ 2 are listed:

iCloud CaredDAV

Google CardDAV. (default account)

Ah, after the previous experiment, suspected Google Services were involved

Have seen it suggested elsewhere

To avoid this issue

Create the new contact info on the iCloud account

Then and when needed

Drag that contact entry onto the Google Account

Repeat this process as needed for new entries

An aside but related

Google Services work well when used on Android devices

Apple Services work well on Apple Devices

It is when the 2 elephants in the room get together in the same room

Things do not always work out well for the carpet ( humour here )

To try and determine just where this problem may be in creating a new contact .

Take the  computer Off - Line ( No Internet Connection )

Add your contact information

Does it work as expected ?

Yes, taking the Macbook offline stopped the glitching - it works as expected. That is a very inconvenient way to add a contact. It used to be flawless.

I agree, totally 👍

Hate to bring this up but in good conscience we must

Is Contacts application using 1 Cloud Based Source or more than 1 ?

If so, which Cloud Based Source( s )

That all makes sense

Very Best in the future
