My app at some point ceased to open in "Edit Mode", but it works fine in "Play Mode". This problem appeared on the last week and still it is not solved. Therefore, I can not edit my app now and make changes to it. Can you help me?
Could you please share a bit more about the issue on your side?
Further, could you please share mode details about the error message when you edit/open your app in "Edit Mode"?
I have made a test on my side and don't have the issue that you mentioned. I could edit/open my app in "Edit Mode", the GIF screenshot as below:
Please take a try to clear cache of your browser, then try your app in "Edit Mode" again to check if the issue is solved.
In addition, you could also take a try to open your app in "Edit Mode" within another browser, then check if the issue still exists. If the issue still exists, please consider take a try to re-create a new app on your side.
