Data names can only contain lowercase characters ( a - z ), underscores ( _ ), and numbers ( 1 - 9 ).
Broken Logic
Conditional logic was broken when fields were removed from your app.
Field that was being used as logic for another field was moved into or out of a repeatable section.
Missing App Elements
There is a section or repeatable section within your app but there is no fields contained within that section or repeatable section.
No name has been provided for your app.
