Though Flash was once upon a time a dominant platform for online multimedia content it’s now being abandoned as Adobe has decided to transition to HTML5 by end of 2020. Therefore, if you have already not started transitioning of your eLearning courses from Flash to HTML5, then it is time for you to trigger Flash to HTML5 Conversion
In July 2017, Adobe announced that it would end support for Flash Player at the end of 2020 and continued to encourage the use of open HTML5 standards in place of Flash. The announcement was coordinated with Apple, Facebook, Google, Microsoft, and Mozilla. (Ref: https://en.wikipedia.org/wiki/Adobe_Flash_Player)
Therefore, imagine if you had put in all your efforts and handwork in creating the content and then got them converted to flash eLearning courses. After the support of Flash Player is withdrawn, your courses will not play on the browsers and all your efforts would go waste. So, you should start converting your Flash Based courses to HTML5 Courses.
Support from Adobe and the Web Browsers is just one part of the story, let us look at 7 reasons.
