We are limiting blueprint descriptions to 100 characters.
To safely display the entire text for template cards. Here is where the blueprint description is located:
Make sure your Connect blueprint description does not exceed 100 characters. We have done a check with existing apps, but additional validation is recommended. If your description is more than 100 characters, an exception will be thrown and the app will not be installed.
We released these changes to the developer first release cohort on March 16, 2021 and will release to production on March 23, 2021.
