@Amanda.Schade @SkyeEden there are at least 2 bug fixes related to LyraStarterGame listed in the 5.0.3 release notes you posted.
However after updating to 5.0.3 I see that LyraStarterGame content has in fact not changed at all.  Creating a new Lyra project yields exactly the same result as in 5.0.2.  No updates have been released for it.
Is there a subsequent Lyra update that has not yet been pushed out?
If not, perhaps the release notes are wrong?
Please and thank you for any insight you can provide.
Edit:  In the 5.0.2 update, after updating the engine there was also an option to update the LyraStarterGame content, but in 5.0.3 there is currently no such option.
