Can't play much hours on GeForce NOW because of "Too many devices" problem

Hello, i play Apex Legends only on GeForce NOW, but soon i encountered a problem: when playing much, at some point an error can appear. Error code: 10502, its something about too many devices played this game. Why is it so? I am playing the game on GeForce NOW, why is there some restrictions while playing it? You shouldn't have added this game into GFN service if this error is active. Can i fix this somehow?
