Hi Joy,
Thanks for your question - you are in the right place! Sorry that it is currently difficult to find 2021 training - we are working on redesigning that webpage to make it easier.
Here are some good options for FME Desktop 2021 training:
The first half of the Integrate Data with the FME Platform is focused on FME Desktop. It's our recommended introductory training for the FME platform. You can view the video here, or view the instructions and videos together on the FME Academy (sign up here, then access the content here).
We are offering the longer FME Desktop Basic course as a free live 5-day training course later this month. We will be recording that and posting the recordings in April. You can take that content self-serve in the FME Academy as well.
If you want an even faster and high-level introduction to FME, we are offering one 90-minute FME Accelerator per month.
I hope that helps - please let me know if you have any other questions.
