What do you mean by not seeing replies on Primal iOS? There is Latest with Replies feed which you can use to see all notes on the home screen. And if you set it to be the first feed in the Feeds Settings it will be the default feed when app opens.
oof on the mansplain. I get where you took that literally and misunderstood. So let me clear this up: I don't see all of the replies. Primal misses some of them, which I didn't realize until I went back to Damus and saw the replies to my notes I'd been missing. Pls don't ask for screenshots. (I did see someone else on here with the same problem and they made a video of it. No, I don't remember who it was, but I'm sure you can find it if you found my note).
