You must be careful, it can also depend on how your appliances are set up.
In my environment, we have 3 appliances. The admin appliance, and two user appliances.
When I first deployed BT, I had an issue just like yours. Services would show up and disappear at random.
What was happening was, when the load balancer pointed me to the end user appliances, admin features would not show up, things like Account Management, etc. but when I hit the admin appliance, the icons where present.
My solution, I placed the two end user appliances on the load balancer with a URL of something like https://users.vault.com and then the admin appliance was stand-alone and I had a separate URL for that.
If you are a cloud user, no appliances on premises, then this obviously isn’t your issue.
