I am using portal 7.1 and a portlet based on the appprovider provider. This portlet is defined at the organization level, so all users are supposed to have the same apps available. But for some users, don't see the news apps as I update the content of the portlet. I am thinking this has to be related to a cache issue. But I have no idea on what to do to try to solve the problem. I hope some of you already had this problem and found a way to solve it.
