I also had "Presenter keeps asking for Flash Player update (Office 2016/365)". I did apply the temporary fix (see Emily Loyd Jun 17, 2018 post) and it "solved the problem". But... that put my Office version back one or more versions (because I had to turn off auto updates and to revert to a previous version), which concerns me. And Adobe has not announced a more permanent fix.
I have been using Presenter to create lessons for an online course -- so, it is becoming more obvious that Presenter may adversely affect the course. If I have to turn off auto updates for a non-Adobe product (i.e., MS Office), that should concern Adobe. I may be forced to find a replacement for Presenter.
