## Callsign Reviews in United Kingdom

### **--- "Guest68"
I can’t complete the registration process because when I enter 4 digits, it comes back with an error message “entered data is invalid.” I can’t see why 4 digits is wrong. 
At the same time, the Callsign id I entered as the first step of the registration haven been taken. I  tried multiple times and get the same error. I guess this has created multiple rubbish records in its database.

### *---- "Cumbersome to use"
On Mac it is a pain to login. 
The app keeps opening Safari even though my default browser is chrome. 

Then it's unable to sign in with Safari and one has to do a copy and paste dance from one browser to another to authenticate. 

This happens across our whole department and is a waste of time and immensely frustrating.

Connection can drop when ever it feels like, some days are wide then others but please for the love of God make the authentication work better.

### ***** "Very good app"
It's a good app
