Strike doesn't allow you to receive BTC and it remain in BTC. When you request it will generate a lightning invoice for the amount in dollars converted to sats, that amount will then be auto-converted to dollars upon receipt. You can send L1 sats out from BTC balance but not receive L1 or lightning funds and have them remain as sats. You can however go buy sats with the $ received over lightning and converted.

Wow. Thank you for the clarification; I'm guessing this was a recent change. Can't say that I agree with this change in functionality. 🙁
I think it's been this way for over a year now.... Strike is pretty ridiculous, they also only give you account statements by the month which makes taxes a nightmare; apparently you can "request" a yearly statement by emailing support, ridiculous they do it that way though.
I've actually been receiving LN payments through CashApp for a few months now, that's why it seemed weird that the functionality was gone suddenly.
