Thank you for the quick response.
I think I did not have any downloads running.
Although you never know if a game or so updates in the background.
Streaming from DLNA worked.
Maybe just a hickup. Will try again when time allows and let you know.
As I updated/downloaded from store and did not check sidequest version again before im not sure if it would have behaved the same.
But if it works for you im quite positive in worst case a factory reset should fix it ✌️
