I have recently exprienced an issue where my webcore cant create a piston at all. tried loading the new version of webcore but i’m not able to see the new version of webcore on my smartapps only can see the older versions.
Try opening your instance of webcore in the ST app, go to settings and select rebuild and clean up data cache. That should resolve that issue, if not, logout of the webcore dashboard and log back in.
Need more data. If you installed newer version of the code over the old code in IDE, you would only see one webcore in the app so unsure what you mean by only seeing older version vs newer version. If you somehow created separate copies of webcore in IDE, then that would be bad… very bad and cause unexpected results and errors.
