I understand browser-based Flash apps will become unusable at the end of the year when browsers drop support: https://blog.adobe.com/en/publish/2017/07/25/adobe-flash-update.html#gs.jasqm6
Extended support for Flash applications, including a new Flash runtime, is available through a license with Harman: https://services.harman.com/partners/adobe
My question: what happens to existing Air applications with a Flash dependency in 2021? Will they continue to technically function technically, but run unsupported?
More specifically, would it be technically feasible to port a browser-based Flex 4 application to run as a standalone desktop Air app?
