Bought the stick during prime day. Worked as expected on the first day (watch movie and tv from prime, installed iView, channel 7, 9, 10 and SBS apps). Didn't use it for a few days. When I tried again, the stick started to restart when first power up. Usually after several power up/down attempts, it was able to reach the home screen. Today I did a factory reset and reconnect to my amazon account. The stick now restarts endlessly and it was not able to reach the home screen for 30 minutes.
Updated on 27 Oct 2020. Left the fire stick alone for a couple days. When I tried the fire stick again today, I was able to boot to the home screen and watched movie. It is doing what it is expected to do. Change the rating from one to three star.
