Swap BTTOLD to BTTNEW from Binance exchange

Greetings people,

I can't seem to manage swapping my BTTOLD to BTTNEW manually since I hold them on my binance exchange wallet.

Even if I send them to my Metamask wallet, the amount does not appear in the BTT swap on their webpage.

It wants to connect to metamask, but then connects to binance chain wallet instead.

Anyone out there who already managed to swapp BTT held on binance?

thx for your help
