Yes when switching vpns you should see the IP address changing on the top right hand box
Morning - no, i get the green ball going round and round and then it stops on full green but do not get any IP address, ping etc.
I uploaded the config files from the link you provided and then transferred them using Filezilla into the hdd/surfsharkvpn2 and when I rebooted the box this is the screen I had - it looks slightly different to the others screens where countries are actually listed, i.e USA or UK rather than in code.
