If I click on the Downloads button in the Hub, I get a page that lists the 1.2 updater.
If I go to the Steinberg Downloads page for Dorico Pro, I get a different page.
Perhaps the Hub hasn’t been updated to reflect the change of name/version?
This thread: Checking for 2.0 updates takes me to a 1.x website - Dorico - Steinberg Forums is still showing on the first page of topics, at the time I post this.
I know that it’s hard to search this forum but please at least read down the first page before starting a new thread…
