Adobe Presenter - Office 365

Unfortunately, that seems to be the state of things with Presenter. Most of us long time users are not happy, but that is the direction things seem to be going. Version 11.1 was released in December of 2020, and before that Version 11.0 was released in June of 2018. It clearly isn't seeing any attention from a development/update perspective. 

Release notes can be found here, to show the slow movement of progress for this. https://helpx.adobe.com/presenter/presenter-releasenotes.html 

It's not that your HTML projects will suddenly become obsolete, but rather that it is probably time to start planning on moving to a different application to ensure you are able to continue producing the content you need. 

I believe the answer is yes, but... 

Presenter is reliant very heavily on Flash. There are still parts of Presenter that can be used today, but it is most likely an orphan product at this point. I'd not expect to see any updates/fixes for it in the future. 

If you need a PPT plugin tool, I'd look to another option. If you want an Adobe eLearning creation tool, I'd look to Captivate.
