Are you accessing over Tor? You may need to send it through Orbot if so. Last I checked Bluewallet stopped doing Tor natively within the app. I hope that helps.

Nope; I did know they removed native Tor.
To activate the LDK wallet, you used to spam 10 times the Lightning wallet button in the bluewallet "Add New Wallet" menu
But its gone now 😥
