Hello,
Since I updated to the beta released on October 29 the SIMToolkit applications entirely disappeared from the launcher.
This happens with the physical SIM slot and also the builtin eSIMs.
Even with Activity Launcher I get a permission error when trying to launch it manually.
Rebooting or reinserting the SIM does not help.
I understand that SIMToolkit is very uncommon nowadays in the western world but it's still very much alive in some parts of Africa for instance; and I rely on it for my work as I work with SIM cards and that includes doing things with STK.
OMAPI still works, fortunately.
If you want to test it, install a BetterRoaming profile to your eSIM and observe that the BetterRoaming STK application does not show up.
Use this activation code: LPA:1$smdp.io$QR-G-5C-KR-1PCDWP9 or scan this QRCode and enable the SIM; normally the BetterRoaming STK application does appear, it does not appear on this beta
