I delegated to 0xb1 / PlusMinus but I can't see the KT1 address in the wallet

I am trying to undelegate it but it simply doesn’t show the address anymore in the wallet. How can I undelegate and find another baker?

I am using the linux version of Galleon (latest available in snap store is 1.3.5b)

Unfortunately linux builds are not temporarily supported.

Please follow the instructions at Migrating from Galleon to Another Tezos Wallet to open your account in Umami wallet.
