I have added multiple servers in WAC with no issues but when I provide the web link to my coworkers to access WAC, they are able to access but not able to see any servers which I have added, do all the users need to add all those servers separately? Ideally all the users should have access to all the servers which has been added in WAC.
So yeah, this is definitely a limitation today... I think it's one of the highest feedback items over on Uservoice. Hopefully it's something they're working on, because it's a pain for onboarding new admin users.
