Hi everyone,
Recently, there has been a site wide glitch dealing with the above for some of us. One example of the glitch is trying to get alerts and messages. The other is trying to do replies on polls and clicking on the like button. The HU Support Team is aware of the issue(s) and are working on fixing the problem as fast as they can. Please be patient. These have also happened to me for the last few days.
