Unfortunately, it looks like Fedilab is a mobile app only.
Also, I've installed it on Android and the default does not show the OP above with replies grouped below.
Looking at its settings, maybe one might affect completely missing OPs, "Remote Conversations". I've enabled it and will see how it goes.
I can't find any setting to make it show replies grouped below the OP.
Thanks for the in-depth info.
I'm kind of amazed they released a system that shows replies but not necessarily the OP! But presumably there's all kinds of technical reasons over my head.
I've installed Subsitoot and am browsing regular Mastodon (not phanpy) with it... and I can't tell yet if it's making a difference. I'm still thrown by the bass-ackwards layout.
OK, I think I get what I have to do now to see the OP of seemingly orphaned replies, and also to see all replies to an OP, below the OP.
That finally shows me both the OP, at top, and all replies, below.
So, a bit of a palaver but doable. Thanks! Hopefully, future versions of Mastodon will make getting posts and displaying them properly grouped in the main timeline easier.
