No Thumbnail On Thunar While MTP Browsing

I’m using thunar 4.18.8-1 (xfce4) with tumbler 4.18.1-1.
I have enabled thumbnail with “always” and “no [size] limit” in thumbnail making.
Works like a charm for local files/pictures. But not working when I try to access my smartphone files over MTP.
I have tried with tumbler DEBUG enabled, and I can see that Thunar is not calling tumblerd when MTP.
Hope I can get some help from the community here.
