You are the GOAT because I ran into that problem before like 6 months ago and I couldn't figure out why the alpha was breaking my symbol into parts instead of flattening it out as one image lol
A stroke of luck that I came across this series of tutorials - taught me a lot! I was being driven crazy trying to learn bones and parenting, which as far as I can tell don't really work. Although I still have some gaps in my understanding of them, seems you can do the lot with just the symbols... Excellent series.
I was watching a video of you a year ago ( about exporting as animated gif ) it processing nice but the save botton is under the taskbar and i can not click it
One reason adobe animate is the worst: i pay for it accidently clises it and the i cant open it again and once i do it tells me pay one i just did. So in other words a huge wasts of money
