Thanks for your reply, Leokan. I did some research since posting this question and found that Harmon is working on this fix in a future build of AIR 33 but as of this week it still wasn't available.
I'll be watching for that fix before we have to start paying Harmon for the Enterprise license. We're holding off as long as possible. Unfortunately our revenues put us into the Enterprise category, even though we are a startup and haven't made a profit yet. We have our apps in the stores so we don't need to get 64 bit Android builds until August 2020 and we will squeeze every drop out of AIR 32. Erik
