It may be your internet or at least the wi-fi connection to your firestick. I'm on Virgin 350 meg broadband and it is sweet as, including the wife streaming HBO in HD in the lounge. Mine is in 4k no stutters etc, though my TV is hard wired and not on wifi. ...Tell you r son to get off his xbox lol
watching mine through WiFi(virgin) on my iPad, perfect so far.......wife is watching Holby on tv, everyone is happy.
The red card has sort of worked for Palace, in that it's turned them into the away side. Sit in, let Bmouth come at them, and counter attack where possible. Palace are nowhere as dangerous when their opponents are the ones who sit in. Hence their usual poor home form.
