How do I get my domain to show my app platform?

I have a domain on GoDaddy that I linked to my digital ocean app platform using the provided documentation. I used the digital ocean nameservers on GoDaddy and now the DNS records are being handled by digital ocean. However I assumed that it would configure everything so that the site would be hosted on my domain that I linked, it now seems that the domain is not resolving after giving it the recommended 72 hours. I try to edit my DNS records on digital ocean and it gives me the message “Record is managed by an app on this account, and cannot be deleted”. Currently there are 2 A records, 2 AAAA records, 3 NS records. I am not experienced at all with networking and would just like to understand how I can resolve this issue. I used DNS checker which shows my records being propagated. There was another previous site that was linked to the domain through GoDaddy, however it is not linked anymore since changing nameservers, I am not sure if this could also be causing the issue. For additional reference, my site is a react site with node.js backend. The link that digital ocean provides for default on the app platform works with my site.
