You should retry. Close and restart QGO, if you have another account on your device, QGO should see it.
Both of your accounts are on the same headset ?
I just try again. I was able to share my Deepseek and Firefox apps to my secondary account
ok, I fixed it - thanks to your excellent tutorial! ADB was RED, but wasn't clear to me this would be an issue as I was copying XAPK files to the 3S using SideQuest - and they installed ok for Primary user. Once I turned ADB GREEN, the Secondary user was available to QGO. As always, your help is invaluable :)
