Wi-Fi too far away
The further your TV is from the router, the weaker the signal. A wall or floor in between makes a big difference. A network cable to the TV usually fixes it in one go.
Too much at once
If the whole family is watching and someone is downloading too, your connection is shared. Count on 25 Mbit/s per screen in 4K.
An old box
Older TV boxes and sticks struggle with 4K. Choose Full HD in the app, or replace the box with a newer Firestick.
The app itself
Update the app to the newest version and restart the device now and then. That clears the memory.
