Can you be more specific?
I experience no problems navigating the GCP Console UI.
Though I mostly do not do it -- I have stuctured bookmarklets for everything I use and it works really great. And also I use gcloud and Terraform a lot.
I have very little experience with GCP as not much of an infra person. However, for me the most annoying bit is how the profiler is using its welcome screen as a loading indicator as well as 'there is no data' page. Makes it very hard to browse data.
GCP support also provides the answers I need.
