AppDesigner .mlapp save r2016a compatible version from r2017a

2 views (last 30 days)
Hi, I've developed a mlapp in R2017a. However, I can not open (to edit) on R2016a. It says "Error loading .mlapp". How can I save a backwards compatible mlapp?
Open the app to run works fine.

It is not recommended to open App Designer app created with MATLAB R2017a in previous releases as it may have new features introduced in R2017a. Refer the release notes here
Follow the workaround provided on this page to open the mlapp file in R2016a.

Thanks! I did not realize how new AppDesigner was. I had to force a few of my coworkers to update to 2017a. Hopefully MATLAB keeps developing more features into AppDesigner! In my humble opinion, it's easier to work with than GUIDE.
