ANE LAB is unusable in the last version (fails on windows to copy framework files for iOS). Firebase is not updated regularly, I had to push them really bad to update once this year. Firebase ANE was 20+ versions before the one available. Then they released with several crashing bugs.
After reporting everything they have disappeared with no response. It has now been more than 1 month with several kind reminders to help me but sadly I get no support (which i paid for).
I decided long ago that I will move to Distriqt as they are very responsive and always helpful.
ps. Fun fact about Milkman, the other day, I was looking for an old ane and I saw that they actually still run Google Ads to get new users, even though their ANEs are not working any more.
