[Lizmap] Dataviz - Limitations?

[Immo Blecher]

Hi,

reverting to 3.10 will be difficult as the QGIS server is on an external 
server on which I have little control. But maybe I must mention that I 
am on Desktop 3.18 and the server on 3.16. I could maybe go back to the 
LTR desktop and see what happens.

But also during the process I upgraded the Lizmap plugin...not sure 
whether that made a difference. But I also noticed that the "display 
children" in the popup does not work (it also used to work). So 
somewhere there is a problem with detecting the relationship?

I will try a few things, including updating the server and provide 
feedback if I find anything worth noting.
