Apps: Goodnotes 4, nPlayer Plus
On iTunes store it says these apps "Requires iOS 8.0 or later. Compatible with iPhone, iPad, and iPod touch."
I use iOS 8.4 on old iPad 2, 32bit.
These apps downloaded from this site don't work. When run they just die, and when run from command line ssh they get "Killed: 9" immediately.
Older versions of these apps from this site work on iOS8. They had "os80" "univ" in their ipa filenames. Newer ones don't, and mention "ok iOS 11" in the ipa filenames.
What is preventing the latest versions from working on iOS8? Did something change in the way they are cracked to only let them run on newer iOS versions? Can they be cracked to work on both iOS8 and iOS11?
nPlayer 3.9.3 works, newer 3.10.* versions do not.
"nPlayer_3.10.5_iOS 11 OK.ipa" does not work on iOS8
Goodnotes 4 12.21 works, newer versions don't.
"GoodNotes_4.13.2_iOS 11 OK.ipa" does not work on iOS8
"GoodNotes_4.13.3_telefonbuch\ ok\ iOS\ 11.ipa" does not work on iOS8
Edit: I just randomly found one with "os80" in the filename (it has an orange ios10? tag on the download page): "GoodNotes 4 [Time Base Technology Limited] (v4.13.3 Univ DY os80 ok11)-user_hidden.rc337uh_102.ipa" and it works.
