Normal homepage on fire stick on first use of day. After that I get mostly rectangles. Started when visiting son and using my fire stick on spare tv. His fire stick similar symptoms on different tv. Now I’m back home and same thing happens with same stick. My other stick and tv are fine. Could his WiFi be corrupted?
Yes, tried it a few times & no luck. Tried it again re your suggestion, but this time I
plugged into wall outlet for more power, rather than tv USB port. Two days now & working normal. Thanks for the reminder to try again.
