Straight from my devices. So far I have chromecast from my chromebook, and my ipad and we just set up my husbands laptop and it worked fine as well. Goodness we have a lot of devices! Have you been able to cast anything else or is it just Disney+ that's giving you a problem? Yesterday there was some glitchy streaming but I thought it was probably due to our internet or that Disney was busy. Tonight we have had no problem so far.Through Roku (or something similar), or just straight from device to TV?
