like the title says, a while back there was an issue with the controller not connecting at all, but the 910 build fixed that.
a week ago however now, the steam link menus continue to work correctly, and everything says the connection is active, but once the video stream starts, the controller immediately stops accepting any input while in controller mode, the only thing i can do is hold the menu button and switch it to mouse emulation mode.
then about 10-15 minutes later, it suddenly starts working in controller mode again for no apparent reason.

so far my temporary fix is just to turn the system and stream on before a bit before im ready to play, as by the time i settle down, it might be ready to start working correctly.

was there an update that i didnt notice recently, or is the hardware just reaching end of life?
