There isn't a disconnect. MySubaru is an app with notifications. The website is not.I think it's interesting to note the disconnect between the Subaru recall page, https://www.subaru.com/vehicle-recalls.html and mysubaru.com. The recall page lists 3 recalls for my VIN, the mysubaru site shows nothing. So I think the vehicle-recalls page is a better place to check than mysubaru.com. Maybe mysubaru.com gets updated after the customer is actually selected for "their turn" in the recall campaign.
Subaru is required to send you a snail mail notification as method of notification. That has to come first, as the MySubaru app shows.
