Nintendo Switch logs user out after every session, won’t save credntials
My son requires me to reauthorize his login on another device every time he tries to play

typically it takes about 20-30 minutes to login due to the game crashing, or sign in screen hanging. 

usually takes 3-4 log in attempts each time.

 

completely unusable.
