divlaine Was this for a brand-new app? Or an update to an existing app?
New apps require both 32-bit and 64-bit APKs which can be built with AIR 33, otherwise you get that message as as error which prevents you from releasing it.
Existing apps can still submit updates that are 32-bit-only using AIR 32. That same message does still appear for those, but for updates it's only a warning and not a release-preventing error.
