Bluetooth button is missing in smart connect app

Hi!
I have a Smart Solar MPPT 75/15.
After having it disconnected for a week I was not able to connect to it with Bluetooth. I though maybe I had deactivated it so I bought a ve.direct to usb cable. With that I was able to connect to the device with my phone and laptop. Unfortunately I cannot enable Bluetooth because there is no button in the product info page. See screenshot. Any ideas?

What I already tried:
-Different devices, reinstalling victron connect app

  • disconnecting all cables from the MPPT, waiting 1 min before reconnecting everything

See here also how it looks in the demo:

Hi @Timmethy

When the bluetooth button is not visible when connecting via VE.Direct, the internal bluetooth dongle is no longer working properly. Please contact your seller to apply for warranty.

Kind regards,
