As I dove through all of the trouble-shooting pages online and talked to customer service reps, nothing seemed to solve the issue. My apps were updated. I'd tried unplugging and replugging the Fire TV Stick 4K Max's power supply. To try and remove potential interference, I turned off my TV's Wi-Fi connection and moved all the wireless devices that were between my Fire Stick and my Wi-Fi router (which were, at the most, separated by 7 feet of distance).
