Video material not visible

In the old version of twinmotion i was able to see the video playing on the surface i added it to and scale it to be the right size before exporting. in the new update this isn’t happening, in the edit window i just see the flashing colours of the video and the video only is visible once the render has been exported. i have tried adding a scaled frame of the video onto my sketchup model, a screenshot of the video, but the video in twinmotion is never the right size. this is adding hours onto my work time as i am exporting the video, editing settings, exporting the video, over and over until the video fits which is not efficient!! any advice would be appreciated
