How do I know if a node is private or public? Amboss say which one?
Yeah mobile wallets are different beast. Best bet is (IMO) using private (unannounced) channels. That means others will not use that channel to route payments, but it's still available for your use. Not routing payments means less chance of stuck HTLCs which is the primary reason for unexpected FCs.
There is a "list of good peers for Blixt" maintained by nostr:npub1lxktpvp5cnq3wl5ctu2x88e30mc0ahh8v47qvzc5dmneqqjrzlkqpm5xlc that might be a good place to start:

When you open the channel, you can choose which type. A ‘private’ channel is simply unannounced to the rest of the network: meaning only you, and the node you connect to, will be aware off it’s existence. Most nodes will accept either public or private channels.
Only public nodes are shown on amboss.space, not private ones.
