Cannot open app in editor

I created a app a couple days ago, and i'm now no longer able to open it in the web editor.


It opens the editor tab and then just sits on the "loading" spinner and never loads.


I have a feeling it is something to do with using the Param() function in the app (not screen1) OnStart property.

Perhaps it's waiting for the param input, but as i'm not opening it with the App url complete with the parameter it never recieves it and so doesn't initialise. (Perhaps a bug with using the Param function in OnStart)


I would role back to a previous version, but i put the Param in at the very beginning of the app development so would loose almost everything.


I have no problem opening other apps in editor and the app in question does still "play".


Any help would be appreciated 🙂




UPDATE: Confirmed that when creating new app with the Param function in the App OnStart property, i get the same behaviour and cannot re-open in editor after saving and trying to go back into editor. Feel this is definitely a bug.
