My company is currently using Advanced Roadmaps 3.27.0. The release note for 3.28 says that it supports "Edit sprint capacity directly on your timeline".
For those of you who have used this version, does 3.28 also allow edit of team capacity on a weekly basis for Kanban teams?
Disclaimer: I only know the Cloud version of AR
But I don't think this is possible. As a Kanban team in AR doesn't acknowledge story points. Plus, when grouping by team with show capacity ticked, AR displays the sprints, which is where the capacity is designated against. Kanban has no timebox to designate a Weekly/fortnightly capacity against.
