Custom Workout using Samsung Phone

I have downloaded a step test to my phone
As l use mobile hotspot l cant use a pc for zwift (or so it seems) it will only work using the app on my phone
I can not see the custom workout under training on my phone when l login
Can anyone assist

Many Thanks Sally

I run zwift on android. And afaik you can only add workouts via a computer, dropping file into the correct location. There are posts on how to do this already.

Same with workout creator. Not available on android.
