[disc] mate 20 pro / Jabra elite active 65t

I've ordered jabra elite active 65t headphones and they arrived today. The problem is that even when the headphones connect to my phone and I can play the music, the original Jabra app (Jabra sound+) doesn't recognise that the headphones are connected to the phone so I cannot set the equalizer and other features. Does anyone have a n experience with that? Are there any solutions to this?
