This is about mine and my brothers ps4 his controller connected to mine and now won't connect back so my brother and I both have ps4's and I was playing with a friend when my controller died so I asked to use his and so I played with his main for a bit and he asked for me to switch to his second one so I did but now neither controller is connecting back to his ps I've tried the reset button, USB cords, going to settings and disconnecting and turning off the controller, and as of right now I even unplugged my play station but it's like it's stuck and only synced with mine and the light keeps flashing,,does anyone have any ideas on how I can fix this?

(if someone helps and it works I will post a seperate thing and tell them when to give them as many points as possible(so people won't steal points from this) also please if 2 people answered but you have an idea please please please comment <3)
