I'm curious why the .COMPANY TLD isn't supported. Does anyone know if there are plans to support it in the future? Is there a way to request this feature, like sending an email or filling out a form?
premium domain names are domains outside of the normal pricing scheme of the TLD. They're arbitrarily chosen by the registry, usually being common words/names/etc costing more. It should show you in your current registrar if it's premium or not. Did you transfer in the last 60 days?
I don't think it is a premium domain; it has been with me for the last 8 years.
About the timeline: Yes, Google forcefully transferred all the domains to Squarespace, and I transferred those to Namecheap first (about 10 days ago) and now transferred to Cloudflare. That said, I was able to transfer over 10 domains in the same situation without any problem; only this one is not going through.
