I recently tried downloading Logic Pro on an older device and it did not work. It seems Apple may have done away with this. You can report it here:
Make sure to notify Apple right away... this could be extremely valuable. It's the most effective method to catch the attention of the Logic Pro team.
Submit Feedback to Apple:
Report your issues to Apple. Fixes may not be implemented until they are reported. These forums are user-to-user platforms, and Apple’s involvement is limited to their own schedule. While Apple may not respond directly, the more feedback received, the better understanding they gain of existing issues and potential updates for future versions. Without reporting your concerns, Apple will not be aware of them.

If you know someone that has that specific version of Logic Pro, you may have a shot at accessing it. That is teh only workaround that I have found to work at the moment.
