I wanted to use with my Bip85 seeds, so I tried this with a fresh seed. Phoenix gave warning, but ultimately it worked for me.

They just want to be sure it's not a seed from another wallet that already exists. Use a BIP85 seed and don't use it anywhere else, you'll be fine.

There will be some changes soon when they implement splicing. Personally, I will wait for that to create a new wallet them to ensure I won't have to use the legacy wallet option in the beta. just fyi

Is it possible to setup Phoenix with a seed you have generated yourself?
I was hoping to use one generated with Bip85.
However Phoenix gives a warning to not import a seed that was not generated by Phoenix.

If that is the case what non custodial lightning wallet dies support using a seed you generated yourself?
