custom domin connected to a old account

We had an issue with our WHMCS system for our hosting and at the time we needed to remove Hubspot so without knowing that you needed to disconnect the domain name first before deleting the account. We deleted it thinking it would automatically disconnect all connected apps. Well, it doesn’t seem to work that way…

Can someone from the HubSpot site manually delete that old domain from our old account so that we can add our domain to the new account as well as with Facebook messenger integration? No matter how many times we remove the app from Facebook it still won’t let us reconnect our messenger account. I have seen other posts where people have had the same issues. It’s unprofessional when we send emails not to use our domain name and also as a web design and hosting company we need to be online 24/7 with support and with access to Facebook in one place. Any help is appreciated.

Connecting a custom domain to an old account typically involves associating a personalized web address with an existing user account or online platform. This process allows users to use their chosen domain name instead of the default one provided by the platform. However, challenges may arise if the custom domain is linked to an old or inactive account. I also implement these steps on my website garage flooring anthem
