I don't know if this only happens but most of the long reply I get, or see on other posts, are hidden. I can only view these in the inbox section, and no, it's not my VPN I tried it without too and got the same results. Also on my own posts I simply cannot see any of the parent commwnts (happens on this post as well)
Sorry for the delay, haven't checked Lemmy for a while, The pattern isn't repeated with me, if I could easily share a screenshot of the app I would have shared it.
I always reverse engineer troublesome apps (To put it lightly) to disable the ability of screenshot, among other changes (don't rely on internal feature).
