On third or fourth try I managed to send from WoS to Mutiny with minimal/zero fees via unified QR.
Strangely Mutiny reports: ‚payment recieved‘ while WoS popup shows: ‚Failed transfer‘.
It works. 👍
But why do I need to get the message: „A lightning setup fee of 40,000 SATS will be charged if paid over lightning.Why?“ again in next try to receive Sats even I already have Sats in my Lightning channel in Mutiny?
