I use MATLAB/Simulink R2019b and its new feature: Subsystems Reference.
During develpoment I use referenced subsystems since they are used in multiple models.
Before the models are distributed to customers, the referenced subsystems must be reverted back to 'normal' subsystems for various reasons.
Since MathWorks does not provide a feature for this behavior I wrote some code in order to do it. In this code I use the 'expand subsystem' feature to break the referenced subsystem links.
Now I have to change my MATLAB/Simulink version to R2020a and suddenly the expand subsystem feature no longer works for referenced subsystems. This change is not documented in the release notes or anywhere else.
Has anyone an idea how I can change my referenced subsystems back to 'normal' subsystems without copying the whole content from one subsystem into antoher one?
