I can't find an option to extract SBTC, the website tells it does, but an actual option is missing to select.. Is it suspended or what? Or I missed smth.?

SBTC is now back online. It was previously down for maintenance.
I have problem claiming SBTC , BTX, BCX, BCI, UBTC and BCL i'm using the BIP39 Mnemonic option and i'm getting the following issue : A transaction could not be updated
