I have basically now setup in Unity & find every version update of the Unity engine doesn’t break the bridge I need working, it’s a pity I won’t be basing my main projects now in Unreal because every version just doesn’t support bridges or older projects very well.
Unreal & Unity both have advantages and disadvantages but i find the biggest drawback to Unreal is the version noncompliance & incompatibility with plugins and older project files.
