Update: Apple rejected Delta 1.6 from the App Store due to it including a link to our Patreon (despite the link being there since version 1.5.2)
We've submitted a new version without the Patreon link and will update you once we hear more!
Non-PAL AltStore users can sideload Delta 1.6 in the meantime — apologies for the delay https://fosstodon.org/@altstore/112764037770811929
