...Internal Transitions that was marked as @hide in the platform are recolor, rotate, change text and crossfade. As well as two extra transitions, which are scale and translation. Migrate to AndroidX! Support libraries are not updating anymore, to get all the bug fixes you have to use AndroidX transitions. Replace imports for all the classes which are a part of the AndroidX lib. Some setters in AndroidX transitions are not following the builder pattern, please rewrite this usages with introducing a helper variable if you encounter the issue.
