Advertisements Just got a stream 4k and hbo max is sluggish, and pauses/buffers at the beginning of a new show. Horrible experience. Internet download speed tests at better than 300 Mbps. On the same device I have Netflix and it has absolutely no issue, so this should not be a wifi issue, either. TiVo streaming app, youtube, etc., all work fine as well. Only problem is HBO Max (which is why I bought the TiVo device in the first place). Any ideas?
