That’s good to know; just tried it out. What’s odd is that (1) lightning addresses can’t be used from the “send” feature, only “pay” and (2) an ln invoice inputted in the “pay” screen can only be filled from a USD balance held on Strike, not a bitcoin balance held on Strike. Anyway, thanks for the tip.  

You can easily send your money to any lightning wallet: tap "Pay" on homescreen, select QR code icon top right and just pay any LN invoice. 

They just don't call it "withdraw", because that wouldn't make sense for LN payments. 
The BTC tab is for stacking larger amounts and there it makes sense to do onchain.

Yes. I asssume there’s some dynamic at play that explains the decision to allow withdrawal of bitcoin held on Strike to an on-chain address but not to lightning. Strikes (lol) me as odd given Mallers very vocal ln advocacy. 

Are you asking about withdrawals to on-chain wallets?
