Does anyone know for sure if the store officially opened? It says open but no announcement was made

It's not officially open because I thought the same thing. If you go on their website, you can sign up on their newsletter and they'll give you details about when they'll open.

I went to the store in August 2021, can confirm they’re open now and have been operating since early June.

They open June 3. They had 2 days of previews for fan club members.

June 3rd
