The settings for playing via sony remote play on a PC have not been fixed, only the R1 and L1 buttons can still be mapped. L3 does not work. This only occurs with Destiny 2 after DLC Beyond. Other games work normally, so the problem is in the Destiny application, which misrecognizes the client and probably thinks that it is PS Vita, so the buttons are missing and cannot be remapped. I am attaching a picture.
Correct BUG !!!!!!!! unable play over Sony remote play on PC, same is Tablet remote play on IOS
