Photoshop don't send pictures back in lightroom

The missing "recent files" on the Photoshop home screen is a bug and separate issue, unrelated to Lightroom. It will most likely be fixed in an upcoming update.

If you open Lightroom the files will be there, as long as you follow the guidelines posted above.

The roundtrip requires that you use the Edit in Photoshop to go from Lr > Ps, and then use a simple Save, and not the Save As.

I hope this helps.

In Lightroom, are you using Edit in Photoshop, or exporting an image that you open in Photoshop?

For the image to return to Lightroom, you have to use Edit in Photoshop.

When saving in Photoshop, do not use Save As, just Save.

If the image does not seem to return to Lightroom, make sure that Sort is set to File name.

The default sort order is Added order, which will display the image at the end of the Library,

Also photoshom can't shom me the picturs from my cloud lightroom in the opening screen. 
Any ideas of how I can fix it ?
