I remember I can set chamber fan, part fan etc. I can still do it on my phone app and on screen but on desktop, looks to be disappeared.
I noticed this too and i find it quite anoying. I seemed to have been changed after an update or so. I hope they will bring that control back in a new update because for me controlling the fans is important (with aux fan on my parts warp). Maybe someone has an workaround/idee?
I need it back too, because i upgraded my X1C with a chamber heating. Really annoying.
It is back! Last update fixed it!
