In both variants of installation Quick and Advanced, I have met the same issue with detecting snaps.
It is important because slow sync can take a lot of time to get on track for the validator.
In advanced mode, you can add seeds manually. I have listed all seeds from testnet-2 readme.
But deploy failed to find any snapshot.
The only option that worked for me is to deploy in quick mode iterating through seeds until snap obtained.
