Adobe Flash may not be supported on the latest iOS and Android devices but there is a pretty easy workaround.
There are a number of browsers that claim to support Flash, but we have tested and recommend using Puffin Web Browser:
You will definitely want to ensure you are on wifi when you take any training.
If you want to try it out, simply search for "Puffin Browser" in the App Store, install the app, and launch this browser whenever you want to do training in Workhub.
We are in the middle of converting our training from Adobe Flash into HTML5 and this workaround will not be necessary when that is complete.
