3/31/2021 original review: Garbage. Downloaded to update firmware on my Q70T soundbar and when I ask it to update it immediately comes back and says it was interrupted. Will not download or start the update process. I tried to manually update with a thumb drive but the soundbar has a micro USB and needs an adapter. Thanks Samsung, I'll never buy your garbage again Update 2/1/2022: same issue in latest app version, no changes, still sucks. Also, cannot use the app to update the TV firmware.
