Opening Canvas App in Edit mode takes excessive time to open

Problem: Two Canvas apps in my enterprise portfolio took over 20 minutes to load in edit mode.

Initial Hypothesis: If I specify the version of a studio in the URL to an old version, the offending app loads in edit mode in under a minute.

&studio-version=v3.24052.30.298708436 onto the Canvas app edit URL

This tells me that something in my app is offending when the latest studio versions are used to edit the app.  While this was okay for a few weeks as a workaround, MS support eventually gave me two settings that fixed both my apps.

Resolution: 

• Turn off "Collection access in component scope"
• Turn on "New analysis engine"
