I can't upgrade in GUI. Same in CLI:
root@nas3[~]# cat /etc/version
22.02-MASTER-20220205-112923
root@nas3[~]# cli
[nas3]> system update update
[0%] Retrieving update manifest...
[0%] Verifying existing update...
[50%] Reading update file...
Error: Unable to downgrade from 22.02-MASTER-20220205-112923 to 22.02.1-MASTER-20220207-152925
So how to switch train to 0.2.1-MASTER (or to stay on head) ?
