The unity collab button doesnt appear on the editor
Im on a project with collab enabled, there is no collab button, i can enable the service but the collab button doesnt show. please help... 
Try what they found in this: https://forum.unity.com/threads/solved-i-dont-have-the-collab-button.598609/
Several editor elements were missing for me.
So inspired by the forum post in @Cooperall 's answer, I updated/reinstalled a random package via the package manager. Cinemachine in my case, but that was just the first random pick. Probably unrelated.
Afterwards, all editor elements did load properly again.
