The community member is having trouble setting up a favicon on their Vercel export, as it is not showing up on their website at https://marketing-destination.vercel.app/, but it works on their staging environment at https://marketing-destination-sbnj4.wstd.io/. The comments suggest that the issue may be related to the Vercel configuration, with one community member noting that the list of sizes in the vercel.json config needs to include 144. Another community member mentions they will fix this to add it automatically. However, the solution has not been released yet.
