Hi All,
We have a managed solution that has the managed property 'Customizable' set to true for a number of entities, and false for the rest. For uncustomizable forms it is expected that all edit options are disabled, and you cannot access the properties of any components, but this is also the same for the customizable forms. There is no difference in display or function between the customizable and non-customizable forms
We have uninstalled and re-installed, re-exported the solution, and examined the raw solution XML but can find no reason why forms with 'customizable' set to true remain uncustomizable.
We are CRM 2013 on premise, so could there be something in the backend that needs checking out? Happy to provide screenshots if necessary
TL;DR all form edit options are disabled for customizable managed forms.
