Currently in ship 3 block 2 right now. And 90% of what I see are "...". I can see symbol arts and 1-2 people's actual area chat. But the vast majority is just "...". Changing stuff in the xbox privacy account doesn't seem to do anything, even though I'm on pc. I can see bots spamming just fine as well.

"..." usually means that a symbol art or chat message was blocked, or the person is just at the edge of chat range. There's a reason why symbol arts have a hash. It's to help the GMs/etc. populate a blacklist of symbol arts.

... Is typically people barely outside your range chatting. I am pretty sure PSU had the exact same thing.
