Here is my case if you want to hear:
- I opened a Mutiny wallet. There is 0 balance. 
- I don’t have enough money inside Wallet of Satoshi (<100.000sats). 
- I send some satoshi to my Mutiny via on-chain.
- I swapped them to lightning.
- I try to recieve money from wallet of satoshi still gives the not enough money error.
- I transfered some satoshis to Wallet of Satoshi. Now the balance in WoS is greater than 140.000.
- I transferred back them to Mutiny. It left around 40.000 sats in WoS and transferred rest to Mutiny.
- when I try to transfer what I have in WoS to Mutiny, it gives the error: I need to open a channel this is not enough etc…

At this point I understand this lightning stuff is still over my head even though I write software in Python and stuff so not a clueless guy in when it comes to computer. Anyhow I guess we’re still early :))
