Client does not seem to be able to access variables in an instance

Thank you for your answer.
I followed the procedure you recommended but it did not solve the problem. I went as far as downloading the sample projects provided by Epic Games but everything seems to be in order. I did find a few things though.

  1. In the tutorial, they indicate that you have to check the ‘Replicates’ box for a TextRenderer. However, in the case of a Widget Blueprint no ‘Replicates’ box appears.
  2. The variables are indeed defined as replicated in the Game Instance (1) but in the Widget Blueprint the variable is not listed as replicated. (2)

I have tried many ways to solve this problem, but I can’t find a solution. So I am attaching all the changes I made to the variables in question, hoping that you will find the problem.
(3) & (4)
Thanks in advance.
