Missing history button in Edge Stable?

Actually that gives me some hope! Obviously Microsoft haven't rolled it out to everyone and maybe I'm just part of the group they are testing by making us wait longer. I do find the whole thing super confusing and unsatisfactory though because I'm often getting features (in my release install) that supposedly are still in beta but then I'm missing on the History button and the Downloads button both of which appear on all the other computers I support and work with.

It's so inconsistant, you never know what features will be available on a computer and they also don't consistantly follow the version numbering. It's almost like a psychological experiment Microsoft is carrying out on users to confuse them. It also makes supporting and helping people more difficult because you can't have any real idea what features Microsoft have randomly blessed them with. I understand release waves and test phases and how useful they are but they should match version numbers and users should be able to understand what features they have available. This is just frankly offputting.
