It clearly reads as autogenerated reply. It seems ambiguous to me still whether it’s thinking you’re trying to move your domains to squarespace and wondering if google sill keep data or if it’s about them moving domains to squarespace.
Though I’m general I’d assume if you move all your domains out of Google Domains before the transition, there shouldn’t be anything for them to transfer to squarespace.
How is it hard to use? It’s just a list of emojis by type with a search box like any phone.
