I have two questions, basically they both same:
1. What will be the alternative solution for Flashplayer after it gets ended dec2020.
2. And what will be the right solution for exiting websites built-in supporting Flashplayer? will it work after flash player end? or we need to recreate the websites in HTML5?
I've moved this from the Using the Community forum (which is the forum for issues using the forums) to the Flash Player forum.
The alternative solution is to migrate from Flash Player to some other technology. There is no 'right solution' as content providers have different requirements. If you have content that needs to be migrated, contact Adobe's official distribution licensing partner, HARMAN, to inquire about available options.
