Hello,
Thank you for contacting the support, and sorry for any inconvenience that might have been caused due to that.
You should be able to create a GA v3 or a Universal Property without deleting the old one.
Are you able to see this settings page when clicking your Admin settings?

Looking forward to helping you. Thank you
Hello,
Thank you for keeping in touch with us.
Please visit this link: https://analytics.google.com/
From here, you should be able to create a GA Universal Analytics.
Let me know how it goes. We are looking forward to helping you.
Helps to be on the right website. I added my site with both GA v4 and Universal and the plugin can now see my site. Should Analytics have a green dot like Search? See screenshot in link below.

Hello,
Yes, it should. In ‘View’ selection, select All Data and save.
If it does not work, please ensure that you create a GA3 Universal property only and not GA4.

Ensure that it was created as https://
as your site primary is using it.
I hope this helps you with your issue. Let us know if you need anything else.
