I’ve been using ARC for a week now and it’s pretty solid. The only issue is I’ve been prompted a couple of times to log back in. Will you be planning to offer biometric support for the login credentials for Roon ARC in the future? For example, enter your login details once, turn on biometric support and then future logins use Apple’s Face ID to log you back in.
You shouldn’t need to log in repeatedly I’d raise a new support ticket for that.
