Hi @Steven Lawrance ,

We have a community in our org and we are trying to use a custom domain for that particular community alone. Last time we tried this using the steps mentioned in the https://help.salesforce.com/articleView?id=000336819&type=1&mode=1

However, we have ran into issues like

1. Logo Disappeared
2. Incorrect Font
3. Color of the footers changed
4. Self register was not working

So had to revert the changes.

We did research and but haven't found any solutions/workarounds as such. Raised a case with Salesforce but didnt get any pointers. I am not sure if this is the right channel but can you help us in this?
