The two things aren't related. The Aviary not being available on the mobile app is expected at this time. The Sisi questline and all related assets are not part of 1.81 which is the current mobile app version.i realized on the app that the aviary is missing. maybe thats the problem?
people with this problem installed the aviary already?
I do not know what's caused the issue from this morning but a fix is being prepared by the development team.
