Weekend Updates: I cant see my Primary Name
Etherscan tend to run updates on weekends and often times primary names stop showing, or show old names. This is temporary and entirely their UI. So if your primary name is showing on the app.ens.domains, you are fine. The suggestion is to check back on Etherscan in a few days.
If your Primary Name is not showing on the app.ens.domains, review the guide: How to Set As Primary Name
Contract and is not showing the Primary Name
Currently Etherscan do not show Primary Names of contracts, however your named contract will still appear on other sites, apps, etc that have integrated.
