I'm using the lightning implementation built-in on Blockstream's Green Wallet, and they are using Greenlight for the "on-demand lightning node" and Breez as the LSP. Last week I had a swap deposit through on-chain fail to complete (it did get confirmed on-chain). They managed to make a refund possible, but I couldn't say what happened.

I guess that's the state of mobile lightning wallets as of today, we shouldn't be too reckless.
