We have couple of devices that are registered into Platform SSO, and we have been noticing an issue when the user tried to login.
After the users enters the password and hit the return key nothing happens, they need to hit the return key probably 10-15 times in order for the login to happen, the password entered is the correct one and it's just that hitting the return key doesn't invoke the login.
On checking the log of the device one unusual thing that we noticed as compared to a different device where the login is working in a single go is that the AppSSOAgent or AppSSODaemon process were not getting invoked
