Sunddenly App Android Preview send error when, without change, it was working

In Android Preview I got this error (in Web preview all works fine).

I detect the error is poduced when I set a logical variable to true o false.

Few minutes ago all was fine with exactly the same settings.

I detect the error.

For some reason the logical variable was not linked anymore to the visibility parameter of the container…

So the variable exist but when I set it I got this error.

I linked again the variable with the visibily parameter of container and all works fine again…

Huh, that sounds odd. If you have a reproduction of this we could have a look at, please let me know the app id and page!
