[HELP] Pixel Streaming Mouse cursor disappears

This is my latest project. With pixel streaming and I have a problem with mouse cursor (the problem doesn’t exist if I play offline the packaged game):

i created a blueprint to change the wood panels material, selecting the materials from a widget.
In scene you see the widget appears once you step into a collision box and you can change material by clicking on the buttons:

This is the first part of the blueprint, where I get the control of the mouse, when overlapping into the collision box.
Then I make the mouse disappears when I end overlap:

Playing offline I can enter and exit the collision box and the mouse appear and disappear.
In Pixel Streaming, playing with a browser, I enter, the mouse cursor appears, the blueprint works fine, and exiting the collision box the mouse cursor fade out.
But, when entering again… there is no mouse cursor :frowning:

Any thought / soulution to fix this?
Many thanks.
