Thanks for reporting! 👍

Research from @wargcm 🙇:

It looks like it's due to the canSubscribeComments property on the posts, which we get from the backend. For whatever reason, on the Automattic feed, it returns false and from the notifications screen has it as true

It returns false for web too, but I guess they don't hide the Follow Conversation if it's false

It looks like Android may not be checking that property, so it might appear correctly on Android. Maybe we could update iOS' logic to match Android's. I'm also wondering if the backend has changed recently or if it just always returned false for the Automattic feed
