Same issue with the app as well can't get it to go back to the app after the logon, so gave up at that point.Installed it earlier today. Not much to it bar a map and some filters.
Tried to login, was directed to the Octopus login page with the apps browser, entered credentials but wasn't directed back to the app automatically. Closed the browser but profile hadn't been linked in the app, so doesn’t look like I can use it just yet.
