Hello, our editing mode does not work. We have two applications - Tutorpeers and Sparkincubator, for Tutorpeers everything works well, but for Sparkincubator the editing mode does not work. Screenshot attached. I would be grateful for any help in solving this problem.
Hi @Oleksandr_Kocherzhenko Thanks for reaching out! I'm sorry to hear about this issue 
Are there any browser console errors?
Should there be existing queries for this app?
What happens when you click on the component tree (see screenshot)? Do you see a list of components?
If you are missing work in your app, you may want to try stepping back in the history.
If your app has errors or is crashing, we'll definitely want to continue investigating
Also, I noticed the app is in staging, is that expected?
