I’m trying to work through Learn to Code 1 on my iPad Pro, running 12.3.1.I’m still in the early levels, and keep running into an issue where after running my code byte moves a few spaces, the audio garbles and I lose the map. When I try to run my code again I get an error on the first line, “Unable to send commands, missing ’liveViewMessageHandler’”.If I kill the app and start over the level I was on will work fine, but I get the error again a few levels later.Initially I thought this was due to running the beta for iOS 13 but I’ve gone back to 12.3.1 and it still occurs, so its some sort of persistent issue.How I can I get past this? It’s frequent enough that it’s killing any interest in continuing with Playgrounds.
