I created 5 cards buttons on one board, meant to be visible to all Board members. However, I am hearing that users cannot see all buttons. One user can see no buttons, another user can see 3 buttons, but I seem to be the only one that can see all of them. Both users are using Chrome and I have had them clear their browser cache. We just started using the Butler so we are not even close to meeting the quota. Is there anything we need to do to make these buttons visible for all team members?
