Hey, @Mark_Brown_1 !
Thanks for reaching out. I suggest removing the A Record with the Name set as ‘www’. For the A Record remaining please enter ‘@’ into the Name box, and save the changes.
Once the DNS Settings are adjusted, it can take up to 48 hours for the SSL certificate to provision. However, I am happy to check on the status of it from my end in the meantime to be sure it is connected correctly. If you would like me to do so please reply back with the url, and I will gladly look into it.
