Hey @German_Vallverdu , thanks a lot for your post.
You set the Rendering Quality to Ultra, correct? In any case, this behavior looks completely normal to me - we did substantially improve off-screen reflections, but as of yet, there is no way to display a whole scene / whole buildings (depending on the perspective and if they are outside the screen-space), in our reflections. Still, I can gladly have a look myself (if you can share the project with me) if everything is as outlined above. 
hello Demian Gutberlet
Thanks for your quick response
The image is in ultra quality, both for preview and for the final render
I could see in other files that the reflexes have improved considerably and I understand that they are limited when the distances are considerable
In the example I sent you I am concerned about the bathroom sector
In that case, nearby elements are those that are not reflected.
I am going to do a couple of tests and I tell you again how the images were.
Gladly share some further feedback with us, and make sure you have our current latest preview installed as well for the best currently available reflections.
