With the “Faster Play Solo” beta feature enabled, typing stuff in the command bar during a test session displays a “API Documentation isn’t installed properly, please check build log” warning where the autocomplete documentation should be. Disabling the beta feature makes it work as intended.
Repro
Enable the “Faster Play Solo” beta feature
Enter a test session via Run, Play Solo etc
Type anything in the command bar that would display documentation
The fix has shipped, and this should now be resolved. Documentation is now available again in play solo mode under the faster play solo beta. Please let us know if you have any further problems.
