I had Learning to Code 1 on my iPad Air when iOS 10 beta 1 was installed. I installed iOS 10 beta 2 yesterday, and now it is no longer available. Playgrounds says that it's coming soon.
Anyone else having this issue?
Learning to Code 1 in Playgrounds not in iOS 10 beta 2
In mine I saw Learn to Code 1 but with an "Updated" sign. When I tried to open it, it just went to the app store to download the update.
Maybe the update was not available when you tried? You may want to try to launch it again.
It just straight doesn't want to install the lesson anymore. I hope they find this out when they release lesson 2.
