Update project QR

So i have a iphone 4s with latest ios (9.3.1) and latets i2 control v2.2. Iam trying to load a project with a qr scanner app. It recognize the text perfectly, but it wont start the i2 control app. Is there something wrong with the scheme for i2control activation (iridium:// - the scheme of i2 Control V2.2 activation)
