Scenario:
1. Developer "A" has a working WAB app, published to AGOL organization account and works perfectly.
2. Developer "B" takes over WAB app originally built by Developer "A" and has some requested changes to apply to it.
Developer "B" acquires the .zip file of the currently deployed WAB, attempts to "Import" it in WAB Developer installed locally and gets error: "Parse app failed".
Just how does Developer "B" import that WAB to make changes via WAB Developer (local install) and redeploy to AGOL?
Thanks!
