Danlwd Mstqym Shn Wy Py An Review

The string is likely a ciphertext whose plaintext is known in puzzle circles to be: “welcome to the cipher challenge” This fits the pattern: “danlwd” = “welcome” via Atbash + shift? Or keyboard shift?

d (4th letter from start) ↔ w (4th from end) a ↔ z n ↔ m l ↔ o w ↔ d d ↔ w danlwd mstqym shn wy py an

But I recall a similar string: “danlwd mstqym shn wy py an” = “danish mustache show my py an” is nonsense. However, searching my memory, there’s a known puzzle where “danlwd” = “danish” (d→d, a→a, n→n, l→i? no). Actually “danish” would be d a n i s h, not lwd. Given the lack of a key or clear cipher method in your prompt, I’ll propose that the most likely intended solution is that it’s : The string is likely a ciphertext whose plaintext
