Hello again.
The issue is that android has built in security measures against unsigned files above 2 GB. I mentioned this in my first post, but it's easy to miss the part that matters, in this case "unsigned" files.
So yes, you may have games 2GB+ on your phone, but the file you're trying to use is unsigned. Android has no idea who wrote it, it's purpose, etc.
In this case, the advice I gave you is how to fix it.
1) Change the settings on your phone to allow you to run the file. You can do that with google , it tells you specifically how to do it according to the model of your phone.
2) This will allow you to actually see the file you just downloaded.
3) You can attempt to run it, if it doesn't run then you will need to use JoiPlay.
This is the general fix for Android, you can view a step by step of the process here:
